ID this pin? "Lady Lessons"?

I agree with hathorcat it was from one of the comics. I haven't been able to 'pin' down which issue yet though, so if anyone knows, that would be most helpful! I can narrow it down to some, but I don't have all the ones from later on, so can't check the issues themselves!

How neat! Always find something new in the world of pony collecting... when you think you know it all.
