I'm not much of a singer, but I seem to be struck with it too. I'm sure my neighbors have gotten an earful, and for that I apologize. I'm pretty sure I sound like a cat dying when I sing. Most of the time, I was singing that Animaniacs song about the 50 states. That and then I was singing to my plants, some made up song that I just made up on the spot.
Needless to say, I haven't been home in a while. And I think I've lost my voice, so there's going to be a lot of power points in class for the next couple of days.
