Rule #374: When Mommy has to leave the shopping cart to take three kids into the bathroom stall at Wal-Mart and the lady in the stall next to us is really stinky, please don’t get on your hands and knees on the dirty floor, peek under the wall at the lady next door, and yell at the top of your lungs, “Eeewwwww!! It stinks in here!!” Also, please don’t encourage your little brother to join you in doing so.
Rules by the Meanest Mommy in the Whole Wide World 
My four boys routinely try to look under the stall; training them not to is a work in progress.
