Dandruff

I don't think I have a lot of dandruff, but whenever I notice that I have some, I rub my hair for a long while to see how much falls from my head and onto the table or whatever I'm next to. It's gross, but it's also weirdly hypnotic just watching human snow drift down for a couple minutes and pile up. It's one of those little things that's soothing, but I'd be horrified for someone else to see it.
