A single woman is full of potential and, her life, possibility, but she's really just 10 years, 20 pounds, and 30 gray hairs away from being labeled "unmarried." It's sexist (aren't men just eternal bachelors?) and unfair, but it's also totally true. I wouldn't exactly call my 50-year-old, never-married aunt "single." It's kind of like — though not quite — calling a woman over 40 a "girlfriend."
There may be plenty of famous women to challenge the single stigma, but is crossing the unmarried threshold as inevitable as menopause for everyone else? Or should we start minding our Ss and Us?
