This was forwarded to me in an email list of Larry the Cable Guy-isms, and since I'm at the middle school again today, it seemed appropriate:
"Life isn't like a box of chocolates. It's more like a jar of jalapenos. What you do today, might burn your butt tomorrow."
I've recently decided, by the way, that one of the sweetest sounds is that of a boy laughing. Not the usual kind of "Hey did you see the Simpsons last night?" laughter, but that kind of giggling they do when they are well and truly tickled. Music to my ears.
