An odd subway rider:

The morning I go in for more periodontal follow-up work, this (late middle aged) (skinny) (white) guy with a cap pulled down over his head and some earphones or earbuds or whatever on, who ends up getting off at the same stop that I do, and singing out uncomfortably loud to that Rihanna song but otherwise to no-one in particular as he walks along in a very direct straight path down the center of the sidewalk, being all like -

"Shine beautiful /
like diamonds in the sky"
