I know I'm Hot, but...

Why is it that at least 2 out of 3 times a guy has hit on my lately (because, you know, I get that all the time), it has been when I have had virtually no makeup on, my hair is in a pony tail I did not look in the mirror to affix, and I feel ooky. It happened again today. I was coming out of the library thinking about how I hate mean people, and especially crabby women, and some guy was all "hey, beautiful." Really I'm surprised I didn't get some serious flirtage on my way out of the gym tonight, because if the No Makeup Ponytail look is hot , then the No Makeup Ponytail Bright Red Sweat look should be smoking. Can I hear a "How YOU doin?" boys and girls?
