Yeah, sounds like they were both in the wrong--the 15 year old for not wanting to do dishes/chores, and Ahman for probably pushing that a little too far.
We're talking about something here that, quite honestly, could happen to most parents that deal with unruly children. Not saying it's right, just saying it could happen to most of us.
bullsh#t. To all of this.
Both were definitely acting inappropriately and Ahman went incredibly too far and should have never hit her, if it all indeed happened.
As for his second line, I know you're not a parent and neither am I. But, I had a sibling. Perhaps you did, too. I saw my mother and sister go at it sometimes, so much so that I thought one of them was going to lose it one day and hit the other. It never happened. But,
being in that situation, where violence could happen, is definitely a reality for a lot of parents with kids.
Whether or not you act on that aggression is, of course, something else entirely.
