I remember once I must have been looking at someone for too long because she sharply asked me "What are YOU looking at?" I apologized and said " I didn't realize I was staring, I was just noticing how pretty you are..." I was so embarrassed. (We really never know what people are thinking. After she understood I meant no harm, she apologized to me. No harm meant...

On the flip side, as a 55 year old who isn't so buff these days, I couldn't care less when people are looking at me in biking gear. Great freedom in that alone.
