For some of them, yes. Mom never really trucked with that, but she also stayed away from the rest of the world most of the time for other reasons, so it didn't come up. Me, I don't care. If someone has the knack, I don't mind sharing as long as they aren't using it on me.

Might seem odd, since I'm as paranoid as I am, but it's hard to find people who'll follow the old ways anymore in my world.
