I feel as though in the past few years it's becoming more common for me to be interrupted while I'm speaking, and I can't help but wonder if more people are losing a sense of conversational rhythm due to communicating more and more digitally and less and less in person.
When you communicate digitally you don't have to worry about finding the natural rhythm of the conversation, you're not taking away someone else's ability to finish their thought or make their point if you send a message to them while they're still typing. I'm not here to scare monger about the kids and their phones, but it's important that you don't let your skill of finding a conversational rhythm, if you have that skill, atrophy, lest you speak over someone and take away their ability to complete their thought and make their point.
But I also realize that it's really important to specify what I mean by interrupting someone.
When someone says that interrupting is really normal and not considered rude in their community or culture, what they're actually talking about is what's known in linguistics as "cooperative overlap", that or simultaneous talking. Here's an example of cooperative overlap and/or simultaneous talking that you might see in a culture where this is normal and acceptable:
Person A: So guess where I went today? I went to the -
Person B: Oh let me take a wild guess! You went to the shoe store again didn't you?
Person A: That's right, and I got a -
Person C: Oh come on, don't tell you got another pair!
Person A: You know it baby!
Now let's compare that to a different style of interruption, what I like to call "steamrolling"
Person A: So guess where I went today? I went to the -
Person B: UGH did you guys catch the game last night?
Person C: Yeah the refs sucked!
Now, what differences can you see between the first example, aka "cooperative overlapping" vs the second "steamrolling" example?
For one, in the first example Person A is still allowed to make their point, tell their story, and finish their thought. They're not being silenced or completely derailed, and most importantly their conversation partners still seem interested and engaged in what they have to say. In the second example, Person A is being completely derailed and stripped of their chance to finish their thought and make their point, which is unfair to Person A, which is what makes "steamrolling" disrespectful even in many cultures and communities where "cooperative overlapping" would be acceptable.
Now, conversational overlap isn't for everyone, and that's okay, but it makes it awkward and tricky when someone from a community or culture that uses conversational overlap talks to someone who is from a culture that doesn't. For example:
Person A: So the other day I went to -
Person B: Oh my god did you go to that one store?
Person A: Um, no, I went to the movies, and I saw -
Person B: OH did you see that new creepy movie about the aliens?
Person A: No, can I please just finish my story?
Neither person will probably feel great after this conversation. And I'm not here to condemn either conversational styles. I understand why some people see cooperative overlap as a more engaging and exciting conversational style, but I also understand why some people find it frustrating. My mother's family has a cultural background big on conversational overlap, but my father's side of the family ehhh not so much, so I personally grew up seeing these two conversational styles clash a lot.
If you're person A in the above conversation who doesn't like conversational overlap, that's totally fine, I'm personally not a big fan of it either only because I have a terrible memory, so when someone disrupts my flow I usually end up completely forgetting what I want to say. Just try to recognize the difference between cooperative overlap vs steamrolling. If someone is just trying to cooperatively overlap with you, patiently and politely tell them something along the lines of "sorry I have a terrible memory so if I don't finish I'll forget what I'm trying to say". But it's generally a good idea to be more patient and understanding with conversational overlap than steamrolling.
If you're someone who cooperatively overlaps and you encounter someone who isn't a fan of it, try not to take it personally, maybe like me they have a horrible memory and will forget what they're trying to say if they get side tracked.
But what I meant earlier about conversational rhythm is that too often a lot of interrupting comes from not realizing the other person wasn't finished speaking.
For example, personal A wants to say "so the other day I went hiking, and I saw a fox" some people might not recognize when person A is actually finished speaking, typically they assume as soon as they've heard a complete clause that means the thought is finished, so the conversation goes like
Person A: So the other day I went hiking -
Person B: OH I went hiking a few weeks ago with my girlfriend but it was so slippery out!
Person C: Oh how is your girlfriend doing by the way?
Person B: She's doing great! How's your partner doing?
Do you see how this style of interruption, unlike cooperative overlap, also derails Person A and deprives Person A of a chance to finish what they want to say? It's not quite steamrolling, and often just comes from a lack of rhythm or understanding. As a general rule, if you want to avoid interrupting someone, pause for a few seconds after you think they're finished in case they aren't actually finished. This way you avoid accidentally depriving someone of the chance to finish what they want to say and completing their thought.
We should never be too eager to assume someone has finished making their point because you never know what someone might actually be trying to say, and if you cut someone off before they make their point you can miss important context. For example:
Person A: I don't think I see stray cats here -
Person B: AHA BULL FUCKING SHIT! I totally saw a stray cat the other day!
Person A: I was going to say as much as in other places if you had let me finish?
Person A: I hate when it's hot out. When I was a kid it was usually around 25 or 30 degrees Celsius in the summers -
Person B: OH come one don't be such a wimpy little baby! 25-30 degrees isn't even that warm! I've totally seen WAY hotter summers than that!
Person A: Uh, that's what I was going to say if you'd let me finish, the summers were pretty mild when I was a kid, but they're a lot hotter now . .
Do you see how in both conversations Person B was too eager to assume Person A had finished making their point and ended up missing important context? If person B had only paused and waited for Person A to finish making their point, they wouldn't have ended up making an ass of themselves to put it frankly. This style of interruption can make you come across as eager to dominate and "one up" other people, which frankly a lot of people find obnoxious and exhausting. This is different than cooperative overlapping because it comes from a place of wanting to correct or one-up your conversation partner, rather than play and/or build into what they're saying, which is why I'd argue it's closer to steamrolling.
Good conversational rhythm ideally means everyone is allowed to finish their thought and make their point, whether or not that includes overlapping or even simultaneous talking. If you're not sure someone has finished their thought, pause a few seconds to make sure they've had the chance to complete their thought, less you miss important context. OR, if you do interject, it should be about building/playing into what they're saying rather than derailing/steamrolling them.
What's important to keep in mind is that it's often a matter of power and respect when someone is or isn't allowed to finish their thought and make their point. If someone is unable to finish their thought or make their point before getting steamrolled, they're going to feel like their input to the conversation isn't valued or important, and that's never a good feeling.
