I am on Metro North on my way to work. Two rows behind me, someone just took out nail polish and is polishing his or her nails. I am irrationally furious at this, but I'm not sure why. Nail polish isn't gross like nail clippings but..... I feel like my head is going to explode. And if that is not bad enough, I can't make caps lock on my phone and so cannot fully express myself typographically.
