Thank you everyone.  I am one of those parents who likes to know the rules and what is correct so I can reinforce these with my kids.  So many parents think they know it all and pass along misinformation.  This is a problem as the kids get older because more of the rules are enforced and the kids think they are right.
Thanks again.  I certainly received more information than I bargained for!

 Seemed like you all enjoy a great debate.
