When I was a senior in high school there was a girl who sat in the very front row, right in the center of the classroom. Everyday she had her finger jammed up her nose. Sooner or later, she'd take it out, wipe it on her shirt, in her hair, once under her skirt (NO JOKE!). It was disgusting. It would make these juicy sounds ... ugh. So gross. After I graduated I went to Taco Bell one day only to find her working there. Needless to say, I never ate there again.
