The concept of Steve Harrington being a complete and utter control freak because he's spent his entire life being the one to take care of himself.
Like, I'm just imagining Steve going into the emergency custody of Hopper post s2 for some reason or another, and Hopper is so fucking irritated constantly because the kid doesn't listen to *anything* he says,
But he's also so well-behaved otherwise.
Like it's not like Steve's sneaking out or doing drugs or is arguing and screaming. He just– doesn't listen.
Hopper will tell him to come and eat dinner and Steve will refuse but he'll go out a little bit later and make something on his own.
Hopper will tell Steve he has to clean his room (assuming they're in a house rather than the cabin) and Steve won't answer or say anything and Hopper will huff and roll his eyes but he comes back from his shift at the station and finds the whole house clean top to bottom.
The only time Steve argues with Hopper is when it involves the kids.
Hopper will tell Steve to be home at a certain time and Steve will show up an hour or two after that with the excuse of "I was driving the kids to the arcade".
Hopper will "ground" Steve from his car to prevent this, but Steve always ends up stealing his keys back somehow, no matter *where* Hopper hides them. He'll show back up later to tell El about what the kids had been up to that day.
It takes months for Hopper to realize that it's not that Steve doesn't respect him, it's just that Steve is still running on his own schedule.
He's up before Hopper in the mornings, eats meals at a different time than him or El, gets home from school at the same time everyday and only disrupts this if the kids need something, he goes to bed later than Hopper would like for a high school student but doesn't listen when Hopper tries to enforce a bedtime.
It's not that Steve is disrespectful or a bad kid, he's just used to taking care of himself, and isn't responding to Hopper's sudden authority very well.
It's different than it was with El, who had defied Hopper immediately and argued for forever because she was used to fighting authority for her safety. And then eventually trusting Hopper once he proved himself.
With Steve, he's never had to fight authority because he's never *had* authority. There's also never been an authority there for him *to* trust, so it takes him much longer to trust Hopper, let alone allow him to actually take care of him.
