When I was on way home from work....I got stuck in traffic. There was 2 gals waving at me continously and I smiled and waved back, they still did it again and I waved at them again and they left on the exit lane to somewhere. I'm wondering why in the world they do that. They look pretty young, maybe late teenagers to early 20's, I don't know.
Just reposting because it was in the other page, in case anyone missed that.
By any chance, you didn't leave anything on top of your car when you got into the car and then drove off? ... that's why the girls were alerting you?
