This is a hair drier story with same moral. For fifteen years I have been leaving my hair drier plugged in, and I hang it around the post which holds the tilting bureau mirror, right over the bureau where all my cosmetics, sprays, etc etc. are. It's in the bathroom and we put a sink into the bureau. So convenient.
Well, I came by the house during the day to pick up some stuff and let the dog out and I heard what I thought was the bathroom fan in our bedroom - went up to turn off the fan light and when I opened the door...there was my hair drier blasting on HIGH! It had already melted one of my plastic bottles! Evidently the cord on the drier is linked to the on-off switch and the weight of the drier pulled the cord which pulled the switch!!
Needless to say I don't do that any more. I disposed of the evidence and have not said a word to DH. I already give him enough to worry about LOL he doesn't need that.
