You're welcome, ass.

I was recently (by recently I mean about 10 minutes ago) driving back from the lab when I decided to be nice and let somebody into the line of traffic out of the parking lot. After all, it was a red light. You know what the driver, after pulling into the spot I so generously left her in traffic, didn't give me while doing that? I guess literally everything could be an answer to that question, but I'm going for a thank you wave here. You know, if you read your history, not getting a thank you wave is what caused Kaiser Wilhelm to invade Belgium in 1914. When someone lets you into traffic, give them a thank you wave.
