Watching how two dogs who love each other will sometimes still nip each other on the ear, bug them while they sleep, etc... watching how cats will snuggle with their buddy all day and then paw-smack 'em in the face, chase them, play-fight...
Makes me, as a fellow social mammal, feel better about my urge to be incredibly annoying to another human sometimes. Like, yeah. Of course I wanna bug you. Of course it's fun to annoy you. We're social creatures and annoyance can be part of play, something we all need. And I watch these dogs who get their ears nipped, cats who get smacked out of a nap, and despite BEING annoyed, they don't stop loving their packmate. After they finish play-fighting, they're back to snuggling and grooming and sleeping together. BEING annoyed is also just part of being in a social group and having relationships... and that's okay. It doesn't erase love or necessarily make them mad or affect them in the long term... a loved one being annoyed with me is a temporary feeling that's normal for social creatures. An annoyance that wouldn't be possible WITHOUT that love
