It looked hideous, so before I went in, I touched it up with some cheap cover-up stick in pale ivory. And that, of course, looked worse, so I tried to wipe it off. It didn't really wipe off, though, because of the dry skin. Instead it just looked like my nose was red with a light dusting of white powder around the nostril.
I can only hope I'm building an interesting reputation at the preschool.
