A few weeks ago I had to buy a new hairdryer. I'm not sure why, but I decided to read the instruction pamphlet--maybe I was trying to see what the "ionic styling" feature really meant and how it really affects hair--in any case, number 7 on the directions baffled me a bit.
7. "Never use while sleeping"
Good thing I "save[d] these instructions" so that I don't try to operate my hairdryer while sleeping.
