Thanks KTPie and KJP! Glad I'm not alone-

My DS9 calls it "thinking" too- smile I just have never seen another kid do it.

KJP I like the idea of chicken armor- in fact, tell your son I'll buy 5 sets please (my hens will thank him).

Regarding not "thinking" in public. I think my DS9 generally controls it in public now, but every once in a while I will see him do it at school. In fact, right now he is having a "thinking" marathon...
