It's all possible because of the shiftmate and it is wonderful. Had I known it would confuse you I would have definitely tried to catch up and explain. I don't wave at all cars, but I do wave at people that wave when they approach me on the sidewalk, and I think this is closer to that sort of scenario.

Enough said, it's a "we're cooler than you" thing. I get it now. Like I said, I won't lose sleep over it and now I know. Thank you, everyone for the help.
