I'm going to get angry at my mom
What did she do that made you feel angry?
Because she was being a total bitch to me!
Getting angry at someone who is already angry at you will lead no where. Someone should be calm and mature enough to argue their points rationally.
She should be able to handle it.
She is still human though, so I think that that best approach could be to calm down a little bit first. Both of you being angry is not going to be very productive.
