I had a phone call with a friend of mine, who told me that a person we both knew had lupus. We talked about it for a minute or two, because I’d only heard about it on house and didn’t know what it involved. Starting that afternoon, I got ads for lupus for about two weeks. I know I hadn’t received those ads before because I play a word game for which “lupus” is a really useful word, and I had not seen its spelling before then.

This was about 15 years ago. It could be a coincidence (but I’m not the age or race most predisposed to lupus), but I’ve been a believer in phones listening to you since.
