As a person with (perhaps incorrect) assumptions about the normal locations for toilet paper to end up, I have to ask: has someone ever had to tell you you had toilet paper stuck to your face? If so...
Toilet paper is a classic technique for treating nicks from razors.
It was merely an example. I have, at various times, had a variety of substances accidentally adhered to my face, head, or clothing. Pointing out something which is obviously unintentionally out of place is much appreciated. Making value judgments on appearance is not.
Why?
