Some of the conductors will actually tell people to keep it the hell down. Some.

One fine morning though, the young lady sitting behind me blabbed (loudly! loudly!) into her cell phone about some man she was mad at.

I finally turned to look at her when I heard (and did not need to know) that it was apparently Jim, and not Brian, who had given her genital warts.

I don't think you're a misanthrope at all.
