If they don't appreciate the power of hurtful words, I think maybe "how to talk so kids will listen..." would be a good book. IIRC, they even have lots of cartoons, so it isn't "reader intensive". Might make them think twice about how they word things.
I'm trying to remember the content of "kids are worth it" (i read it from teh library)...I think it also touches on the basics of GD - why your words are important to kids, etc...if I'm remembering that right, it might be another good book. I remember reading it and thinking "yeah yeah, ITA already"...so it might be a good start for someone who isn't on the ball with that concept yet.
