Growing up, our parents were always telling us what we should and should not do, and reinforced those admonitions with sayings that still rattle around in my head to this day. Sayings like "Don't cross your eyes, Paul. They'll get stuck that way!" and "Don't swallow those watermelon seeds. They'll grow in your stomach." Not only did you get plenty of rules at home, you got a fair share of rules given to you at church.
