I taught myself to braid hair when I was little; I had one of those Cabbage Patch kids with silky hair, and I just kept trying and trying until I got it right. I was always a lot better at braiding my own hair than braiding someone else's. It came in handy during junior high, when I was a cheerleader and french braids were the preferred hairstyle.
I rarely, and by rarely I mean never, wear my hair in a french braid in public. But at home it is not uncommon for me to start braiding my hair and not really realize it. Often I do it while watching t.v. or reading, as if my hands need to find a way to stay busy. Hubby will walk in the room and say, "are you braiding your hair?" then shake his head. I think he fears I will soon be suggesting we get a sisterwife or something.
