AITA for getting angry at my mom’s best friend’s son after he barged into my room?
My mom and his mom have been best friends for years, so our families are really close. Unfortunately, he and I have never gotten along.
He’s 21 and I’m 16, and every time we’re around each other we end up arguing over something stupid.
Today he came into my room without saying anything and immediately started teasing me about being younger than him. I got annoyed and told him that if he was coming into my room, he could at least say hello instead of acting like he owned the place.
He kept teasing me, I snapped back, and eventually my older brother had to come in and stop us because we were getting too loud.
My family thinks we were both being childish, but I feel like he started it by coming into my room and talking down to me.
AITA for getting angry and arguing with him instead of just ignoring him?
