My mom used to tell me this when I was young. "Make sure you mind your P's and Q's" but she could never explain what it means. My understanding it must mean mind your manners or be on your best behavior but what is the P + Q for?
Interesting board by the way and thanks in advance for any help. I'm sure its already been discussed but I didn't find anything with a search.

I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
