I haven't always been afraid to run the dryer, but then I was reading somewhere.. in the comments of something, I think, that someone turned the dryer on and went to church, and when they got home, their house had burnt down, and that you should never leave the house while the dryer is running because it's a fire hazard. And.. I think that it's pretty unlikely that it would happen to me, but then again, I can't get it out of my head, either, so...
