People watching on the train

There's a guy next to me on light rail who's filing his nails. It's a little odd, when was the last time you saw someone filing their nails? Much less on public transportation?

And how long does it take to file your nails before you're down to stubs of fingers?

I almost feel like asking, but looking over, he has the build of a boxer. Squat. Powerful. And the strap on his bag isn't actually a strap. It's inch and a half chain. You don't mess with a guy using 15 pounds of chain to hold a shoulder bag.

And yet he's also wearing a tie. You have to imagine a story there.
