why do boys get mad at us girls when we make a mistake?

Because boys are idiots.
lol I dunno. I've never had any brothers o anything, I didn't know my dad 'till last year, and I get along with my guy-friends pretty well so I've never had much of an experience with this sort of thing.

Rage more.

I don't really think guys just get mad when girls make mistakes....

What makes tu think that anyway? o.o

Not all guys do. Some are kind, helpful and understanding. Others are rude, irritable and insulting. It really depends on who the guy is and what mistake the girl did.

Well I don't know maybe they want their girlfriends to be perfect I don't really know I'm a girl but I have a boyfriend he never got at me
