P's and Q's 

From an old printer's axiom. Back in the early days of printing presses, each line of text had to be set up one letter at a time. Since the letters in the press were reversed (so they'd print forward), the printmaker (or typographer) needed to be careful not to confuse one letter for the other.
Reminding someone to "watch his p's and q's" means to pay attention to the details.

On the stand, Bill was always careful to watch his p's and q's when dealing with the lawyers.

Mind Your P’s and Q’s 

mind your p's and q's

a term used when you are needed a reminder when to watch your manners or mind your own business.

The “P” is for Peace and “Q” is for quite. When you are minding your own Peace and Quiet, you are not paying attention to anything else or dealing with anyone else’s situation.

Don’t pay attention to what’s going on, Just sit there and Mind Your P’s and Q’s

P's and Q's 

This axiom, regardless of its origins, has been common in post-victorian Britain as an abbreviation of 'to mind your manners' or, more specifically, to say both 'please' (p's) and 'thankyou' (thank-Q).
Thus the phrase 'watch your p's and q's' has been in use to encourage people to speak politely, especially children, who remember such phrases better than just instructions.

Kid 1: You spill my pint?
Kid 2: feck off!
Mum: Oi, watch you're p's and q's!
Kid 2: Sorry. Feck off, please.
