Go back to eat in the meadow

Explanation: There's a saying that goes "a good horse won't go back on the meadow he has feed himself", which means that a man with backbone won't go back to what he has deserted or given up. For example, once a couple breaks up, they would feel reluctant to reconcile with each other. Or if a man quit his job but failed to find a better one, he will be ashamed to go back to his former employer. If you do so, you’ll be looked down upon.

Ex.

A: For the sake of money, you'll have to go back and talk to your old boss, see if he would resume your work or not.

B: No way, I would never go back.
