A couple of weeks ago Jessie had another outbreak of "bugs" in her class at school. I reacted by immediately braiding her hair tightly in a cornet and not taking it down for five days. I took it down long enough to wash it, and promptly put it back up again for another five days--while it was still wet. I was in denial.
Tonight while I was bathing J and washing her hair I happened up on... something. I cleaned a bunch of hair out of the comb I used to comb the conditioner through, and there was something... small and black. I had Jessie get out of the bath (I was in it too) and get my reading glasses. I looked closer. It looked like a mature louse--don't ask how I know. J looked at it. She saw an antenna. Dave came in the bathroom and joined in the examination. He was of the minority opinion that it was a bit of schmutz. I wanted him to go to Publix for one of the little metal combs and a nasty chemical shampoo for the J. We were at an impasse. Then Dave reminded me of why I married him.
He took the object in question downstairs and examined it under the USB microscope I got him and the J for Christmas. Happily, he was right (shown at 60 X actual size). Science. It works. And he didn't have to shave his head.
