I was in a house earlier today that had a lice problem. Not a huge problem, but it had been on the heads of two of the little people that lived there earlier in the week.
I did not rub heads with those people, nor did I even touch them. I didn't go in their rooms or hug their stuffed animals or even really have any contact with them, aside from casual, how-are-you sort of contact.
I itch. My head itches, my legs itch, my feet itch, my fingernails itch. Oh, how I hate the power of suggestion.
