That doesnt sound terrible to me. No one can truly annoy someone like their own family. The buttons are hair trigger from all the time around each other. If a stranger did them it might be a little irritating but a family member who should know it bugs you does it and its sand poundingly frustrating. The things you said that made you angry sound reasonable to me. Id be angry too. Im back with my parents and if they didnt go out and away from me several times a week id be foaming at the mouth by now.

It does get better with space or at least it did with me.
