On one of the street I take there are frequently lots of teenagers hanging out. One time, there were ALOT, and they were spilling into the street. I passed by, they saw me, and one put his hand out. I don't know if it was to me, or it was just a gesture, but whatever, I gave him a high five as I passed and he said, "She gave me a five!". Now I'm cool.

Of course, he could have easily taken me down, but I don't think he expected the high five.
