My family argues a good bit. But it's usually just taking the piss out of each other. Seven siblings in one house, six of them boys, doesn't make for a quiet life. You had to yell to be heard most of the time. It's as much a sign of affection as anything with us.
Like I told Stiles -- I'm not going to force anyone to go, but it really is an open invitation for whoever wants to come. It's just something fun and kind of silly to do.
