I didn't stand up to my dad when he spread someone's business around...
Did you know the person at all?
I have some issues with this person and I didn't want to stand up to my dad.
It is hard to stand up to your parents but you shouldn't let them get away with things you know are wrong. People will think that you think those things are okay to do.
I don't really care what people think of me. But I need to be careful around my dad.
I understand not wanting to get in trouble with your father. I feel communicating with them what he is doing is wrong is the best course of action. Hearing it from his son may change the way he talks about people.
