"Give every man thy ear, but few thy voice; Take each man's censure, but reserve thy judgment." - The Bard
It is a line spoken by "the tedious old fool" Polonius – chief counsellor to the villain Claudius - in Act I, Scene III of Shakespeare's Hamlet.
The phrase implies that it's important to be a good listener and accept criticism but to be cautious and deliberate when expressing your own opinions or judgments.

Wise words from the Bard of Avon again!
One thing I notice in a group environment with talkative people, especially after they consumed a few drinks, they tend to respond without listening, or they "listen not to understand but to respond".
I'm not saying myself is better (yes, I did have my own lessons 
), but observing the phenomenon could be amusing and annoying at the same time.
I find that Maowi the cat is among good listeners, as he has two very big ears and is always very quiet and very observant when others are talking. Kudos to him! 
Have a good Monday!
