One of my kids was itching today, but not his head particularly, so I didn't think much of it. Plus, it's the summer and I have multiple kids with mosquito bites all over their arms and legs from being outside in the evenings.
Later in the day, I was walking around to see how they were doing on a paper, and this kid looks up to me, pointing at the side of his neck. "Do I have a flea on my neck?" he asks, clear as day.
And... yes, yes he did. A few minutes later he itched his head and said, "I hope I'm not getting lice again."
I have been itching ALL day.
