Quirkiness

I've been thinking about how wonderful people's strange little quirks are. Life would be terribly boring if nobody had an odd little habit they do regularly.
The other day, I was sitting at a bench at the mall, when I spotted a young-ish man, he couldn't have been older than 25, in a burgundy tee shirt, walking and singing loudly to himself. He strolled by singing some lovely song, and disappeared into the book store. At first, I thought, why, that's odd, because I don't generally see people singing to themselves when they are walking alone. But a few seconds later, after he was gone, I wished I would have stopped him, and at least asked, what song are you singing?
I really liked this fellow-- because he has a wonderful idiosyncrasy of singing aloud. These quirks are great. I love to see all the little eccentricities of the world come out.
