Why?

Why is it that whenever I shave {which lately I have been trying to be better about doing it. Hey, its winter! Noone sees my legs so why do it?!} the moment I step out of the shower I get the chills and my leg hair grows? It makes it seem almost pointless to spend that much time in the shower shaving to just have it grow two seconds later! If I had the money I would go do that laser hair removal. I hate shaving. It takes SOOOO much time and like I just said it grows back the moment I step out of the blasted shower. Ugh.
