Spring is a time of rebirth. To many of us mammals, birth is equated with smooth and naked. According to Sheep 101, sheep are sheared once a year, usually in the spring before the onset of warm weather. Like sheep, us human women who avoid shaving our hairy legs and arm pits during the winter because we claim that the minimal extra body hair helps keep us warmer in the cold winter months, find ourselves exposed. Spring and summer practically beg for skirts, shorts, and tank tops. It's harder to hide our woolliness.
