(my own) voice from the past

Last evening my brother came over to watch the Oscars. While we were having dinner he mentioned that he had come across a web site that was an assemblage of quotes, some from teachers at my school, and that there were a few from me. He could not remember the site, but after some resourceful googling we found it. It was a website of a former student of mine; and he had been collecting quotes for years. When I read this one, I laughed so hard I thought I would choke:

If I were one of those people who talked to themselves, then I wouldn't be here. I would be somewhere else. Talking to myself.

And amazingly, although I said this at least ten years ago, now I remember the situation that provoked it. I was teaching a music theory class. This particular class was quite chatty (and charming, as I recall). I would become exasperated (or mock-exasperated) and produce witticisms like this one. What I found particularly funny about this quote was the student's grasp of punctuation. Very precise.
