Know that feeling all too well... our old warehouse had constant scratching sounds that kept everyone on edge. Turned out to be a family of raccoons in the attic. So much for our exciting ghost stories.

Man, that practical knowledge hits different than textbook problems.

Sometimes the yelling gets so loud you miss other sounds. In my house, the TV would be on full volume or doors were banging. You just don't hear chairs moving when everything is that crazy. Your brain blocks out the small stuff.
