It still happens to me, and just did, that I read or write something on the computer while my background TV says the exact same word or words. This is not a common word that you'd expect. A client just wrote me an email and at the end he asked me if I wanted to put down a deposit on this new business jet. I wrote back "Would 50 bucks do it? I can afford that."
Just as I finished typing "I can afford that" -- the voice on the TV said the exact same words. I don't know what point I'm trying to make but this happens to me all the time.
