Understanding Athelind's Argot: Dot your P's and Cross your Q's

This one should be easy to parse: it's a portmanteau of "dot your I's and cross your T's" with "mind your P's and Q's".

It describes over-attention to detail, to the point where you're "correcting" things that aren't really mistakes.

A more subtle variation is "cross your eyes and dot your T's".
