Fair Game?

I live with a roommate and although, no large quantity has been left behind by either party an abundance of "pocket change" is finding itself into my bucket. My roommate can be very complacent at times but I still stick to "the rule."

Growing up, we had a family rule that if the amount discovered was $5 or less it was all yours. It also had to be discovered, you couldn't hide it or move it to your advantage. Most of my family learned quickly around me that I would not even pass up a lone penny.

Did any of you have similar rules in your family with you growing up? Here's my latest.
