Beauty Sleep

I recently purchased a flat iron for my hair. This is no regular run of the mill flat iron, it somehow works magic (little elves inside?) to get hair looking smooth and soft--other devices don't even compare.

I know how to use flat irons, but I thought with the amount of heat my new one pumps out there may be extra precautions, so I decided to actually read the owner's manual. I flipped through it... Don't use in the bathtub or submerge with water. Check. Don't use on skin, near aerosol, or near an open flame. Ok, that sounds like common sense, right? But what I can't get my head around was don't use while sleeping. ??? Some instance of use while snoozing must have occurred for the company to put that in the manual, but for the life of me I cannot come up with a realistic scenario as to what that was. It makes me giggle every time I do my hair.
