If you have any sort of physique, people look at you because people are people watchers by nature. From the look, different people will assume different things about that person - they may think they are snooty or "on juice" or just be jealous. Some may come up & talk to you about it, some may ignore you for it, some may just gawk & make a comment because it is an extreme from wherever they are coming from - e.g. fat chick, fat guy, anorexic chick, muscle bound guy, hottie whatever.
I recently had a guy ask if I might be interested in him even if he has skinny calves & ankles. I thought that was a strange statement because he's a good looking guy who hits the gym regularly and is very meticulous about his own lifting. But he apparently assumed immediately that I had an issue w/ skinny calves. Of all the stuff in the world, I'd like to think I'm a little less shallow than that.
