I'm not english, so I don't really know how to be polite.
If for example I call a friend and a member of her family answers, how do I ask polite to pass me my friend?
I'm scared. Does it affect me? I live together with my parents and my grandma. My dad always finds a reason to argue, and he shouts at my grandma so hard that sometimes I think he'll punch her.
When he argues with me he always tries to punch me. He told me that he can't wait to punch me again...
