Yeah, that happens to me....a lot. You think I would have learned by now, but you know. Anyways, when I'm on the computer, I always like having music play, quietly or loudly. So turning on the mute button is not an option for that reason, and for the fact that I'll probably forget. But it's okay. I can deal with a one-second heart attack every once in awhile. Keeps me on my toes.
