I sometimes wonder what people are thinking, or if their mouths are actually attached to their brains. I'm not thinking of anyone in particular right at this moment, but if you want an example, here's one:
Older lady (at former church): When are you going to preach?
Me: I preach all the time on Saturday nights.
Older lady: I don't come on Saturday nights. I don't like that kind of music. If you call that stuff music.
I mean, what was I supposed to say to that? Maybe "Shut up"?!?!?!
