I'm going to yell in my bf's parents house
Why do you want to yell in their house?
I thought we were going to stay here longer.
It's inappropriate to yell in your bf's house. Your behavior is rude and unacceptable.
Oh you think this is bad, what if I hit him
Yelling is bad and hitting him is worse. You need to change your behavior to not be so disruptive and mean. I imagine you would not want people screaming in your house for no reason.
