Perhaps this has already been discussed, but I’m wondering about the origin of the phrase “Mind your ps and qs.” I’ve heard it has something to do with typesetting, but I think this is not right. Am I wrong?
It’s been discussed many times. Short answer is “origin unknown.” A few origins are suggested, all unproven, and most of them unlikely.

You can find literally thousands of sites saying the same thing.
Thanks for the responses. I guess I’m at least as right as the next guy on this one!
