Control Your Child

Don’t make store employees or total strangers step in and stop your child from running rampant in stores.  If you want to let your child behave like a selfish asshole at home, that’s fine (well, it’s really not, but whatever).  In public, the child should behave.  Figure out how to make it happen.  If you absolutely cannot do it, leave your child at home.

If you choose to ignore paragraph #1 entirely and have no idea how to control your child, and someone else is forced to, say, stop him from ramming shopping carts into the crotches of other shoppers, say, “Thank you.”  Do not scream at the person for having the audacity to prevent your child from trying to castrate everyone else in the store.  Other people don't want to parent your child any more than you do - unfortunately, you leave them no choice when you act like you have better things to do than be a parent.
