Contrary to rumor, telling your kids the reasons why they should do something, or not do something, is a good practice. You are not caving-in on your authority by telling the youth the purposes behind your directives. Yes, "because I said so" is sometimes the reason, but if you throw that retort into your parenting stew all the time, and sweeten the pot, you are unintentionally teaching that God is a despot who does stuff just because.
