Next time you are in a crowd of people, have a look at foreheads. On the subway the other day, a woman sitting across from me, had about 1 inch between her eyebrows and her full head of dark hair. Another woman to her left had a Glenn Close-type-high forehead. I looked around the car at everyone and how different they all were. Check it out on your own next time. Cowlicks, peaks, small, large, square, everyone one is different and that makes them all odd.
