Reminiscing with childhood friends recently, I was reminded of one of my early teenage grooming habits. When I was 13 or 14, I used to slick Vaseline on my unruly eyebrows in order to tame and "shape" them. Why would I do this, you ask? Well, I got the idea from my equally bushy-eyed best friend. Eventually, my mother grew tired of my shiny brows and sent me to a waxer, but my Vaseline habit made for some interesting yearbook pictures. It's funny to look back on teenage trial and error, and even the best groomed among us has gotten a bad tip or two.
