KillarneyRose, does your father-in-law have a long-lost brother who acts just like him? If he does, it's gotta be my stepdad. He's *exactly* like your description. Now that I'm home for the summer, I will have to stock up on Pepcids because the man literally gives me heartburn.
I second whoever said give the kids lots of sugar and let 'em loose at the in-laws house...at worst, they won't ask you back. Which wouldn't be all that bad, right?
