Fun thread. Naturally, I'm usually too busy checking myself out in any nearby reflective surface to actually notice other people doing it. 
No, but seriously: I do tend to notice the world around me quite a lot and obviously it's nice if someone looks nicely at you. I can't always tell if it's because of how I'm dressed or how I look; probably the former most of the time, to be ruthlessly honest. But even so, as I said, it's nice when you can exchange that kind of glance or smile with someone. But to continue the honesty, I actually don't really pay it much attention beyond that fleeting moment. It's kind of irrelevant to my life, you know?

I didn't look hideous either, but it made me wonder what he was thinking. "Have you lost some weight? Nice threads. What's that stain?"
You could pretty much tell when people look at you and say, "Geez, you're a mess!" or "You look great!" and it was more like the latter. Anyway, I'm not going to read into it any more than I already have.
