Found this strange little white device in my 16-year-old son’s room, and I’m honestly too embarrassed to ask him what it is.

At first, I thought it might be one of those new USB sticks kids use for school. It was small, white, plastic, and shaped almost like a tiny flash drive or some kind of charger part.
