I'm going to yell at my mom for beating a kid in a parking lot
Does she normally beat children in public?
I have a lot of problems with her because she doesn't believe kids should talk back to adults.
Your mother was wrong to beat a child, they are defenseless. You were right to want to protect them, they need protection from people that are bigger and stronger than them.
You're right. I try to calm her down but she goes insane.
You should get her mental help. She shouldn't put her hands on other people's kids no matter what.
