HHHHHHHAAAAAAAAA! Good for your little boy...you're raising him RIGHT, lefty!
What was the other child's reaction? Watch out, you may end up having as much trouble as justinmoon did when his little girl tried to sell lemonade to folks who didn't want to buy anything from her because of justin's bumper stickers! Lots of ignorance in this land of ours, and you and I both know it is often concentrated in the South, where you and I both live.
But I hope your little boy continues to spread the word. Hey, it might get back to that horrible teacher he had last year!
