The only way you can have boundaries is if there is some kind of penalty for stepping over them:
AITA for “leaving” my wife and kids after she locked the door on me?
My wife decided that it’ll be funny to lock the door on me while I was getting the mail. I waited for 10 minutes knocking the door and calling her, and she still wouldn’t answer. I was already pretty pissed that morning because I stubbed my toe and slept pretty terribly. She knew this.
So, I just decided to bike to my friends house. After about 10 minutes she tries to call me, but I just ignore her. After about 2 hours hanging around with my friends playing some Halo, I come back him riding my bike.
