A few weeks ago, I had a pickup acclerate to make a left turn infront of me. I was on the left side of the road because it was a one way with three lanes and I had to make a left. I had to slow and adjust my path slightly, it wasn't a real close call, just unnecessary. Then I heard a horn honking behind me a couple of times. I thought, I didn't cut into traffic, what's the deal. As the car went by me I looked at the driver, he appeared to 20ish. He smiled and waived. Then it occurred to me he was honking at me, he was honking FOR me at the other driver.

That made my day.
