It's kinda fun to watch the look on their faces - isn't it?
Heck yeah it is. I like to let 'em spew for a bit before I let on. It really shows them for the a**es thy are.
I've done it to troll-types on here before, too. Most of the time, someone else "outs" me. Usually, the troll just scurries away and I don't hear from them again. The real stupid ones try to save face, but I don't budge an inch on 'em. ;-)
How have you been? Did you go through an adjustment phase when you got back to the U.S. for good? A lot of people are teling me it's kind of hard at first.
