When I was a kid I would laugh when some one would come over to fix something and my dad wouldn't be able to sit still. He'd go and talk to them and try to help them. He tried to do everything around the house himself, but sometimes the experts had to come (like with plumbing) but that was always hard for him to deal with. As a kid I found it funny.

Now flash forward 30 years and I'm the same way. Go figure. Must be something about being a guy.
