A least good thing about cold weather

You know what both surprises and kinda disgusts me each and every year at the start of sweater season? If it's not sooo cold that you're wearing multiple layers but it is chilly enough that you want a sweater but can get away with wearing it over a tank top or thermal yet sleeveless shirt, it is almost inevitable that you will find sweater pills in your armpits the next time you shower or change and pay attention. Discovering fuzzy black balls in my pits is really quite the surprise. Every damn time. I'm embarrassed despite the fact that I don't believe anyone else has ever seen this wooly residue. It's a notch in the con column to be sure.
