private activities

I was in a class today and witnessed something horrifying. An older student sitting next to me took out a nail clipper and, yes, started to clip her finger nails right there during lecture. It's not even a big class. There were maybe 40 people there. The instructor talks really loud so she didn't hear it (or somehow managed to ignore her). But I was absolutely disgusted and traumatized....yes traumatized. Clipping your nails is a PRIVATE activity that you do, not only in your house, but in the bathroom. There is nothing more disgusting except maybe public nose picking, phlegm horking, or farting. So anyways, this woman was clipping away for a good 5 minutes leaving the clippings on a sheet of paper. I thought, okay well at least she's going to take that paper and dump all that nasty shit in the garbage can, but just as soon as she was finished she picked up the sheet and tossed her nail clippings on the floor next to her desk. Holy shit, I recoiled in horror and damn near went into convulsions when I saw her do that. You know how gross it is to see nail clippings on the floor all curvy crusty and yellowish? But that's not all. She decided to finish off her in-class public manicure by filing. I don't know about you but the sound of filing makes me cringe. In my mind the sound is closely related to chalkboard scratching and I had to resort to plugging my ears as discretely as possible. After the break, I could take it no longer and moved to a desk on the other side of the room.
