Two girls are sitting opposite me on the train. Both have very long nails, and both are picking their nail varnish off with their nails and teeth.
Noise is annoying, and several bits of varnish has landed on my coat!
I would move but difficult to get out, and not much standing room either.
WIBU to tell them to stop. I could always get the nail varnish remover out of my case and hand it them!
