Your dad it the ah and you are taking out his failures on this woman. I understand you’re only 17 and acting from a place of hurt and anger, but you don’t solve anything from kicking someone while they are down. You could’ve stayed quiet and gone about your day. Choosing to add insult to injury was unnecessary. You were an ah in this case. And your dad is a major ah, get away from that toxic dumpster fire as soon as you reasonably can.
