Is it weird to want to fight your Mom?

Well of course you can not beat up your mother. I do feel for your situation though can you move out and get a place for you and your grandmother to stay? You did not state your age either, so I guess if you are a miner this will not work either. How does your grandmother feel about your mother and the way she talks to her? If this is your grandmothers house maybe you should just kick your Mother out. I know what you are going through though because my relationship with my mother is tumultuous.
