I wouldn't ask why she is angry either. I would just ask why they fight so much & I would ask each separately to see how each one perceives what is going on.....the question would be regarding the fighting not the anger.

Anger is a personal feeling & I would definitely stay away from questioning about that.

Glad you are moving out for college. I didn't have that option & living at home & going to college was a challenge. Even when I worked I couldn't afford to move out & get my degree also & my parents had no money for my college & my dad really didn't want me to go. So I blew them off & went anyway but was stuck living at home & it was in a very small house.
