O que significa let one off the hook?

I was listening to the radio the other day when one of the hosts confessed doing something bad three nights before. He dropped a very expensive piece of art that belonged to someone else in the show. The owner had a very positive reaction and forgave him right off the bat, but he couldn't let it go for a minute and kept going on and on about it for 3 days straight. Here's what he was told as an attempt to make him take it easy on himself:

Let yourself off the hook.

When you let someone or even yourself off the hook, that means you allow one to escape from blame, responsibility, obligation or difficulty. So consider that he couldn't sleep a wink since the unfortunate event for guilt and a sense of responsibility. There was nobody blaming him for anything at that point, but he was the one who was beating himself up for not letting himself off the hook.

That's all for now guys. Do you have troubles letting yourself off the hook? Let me know in the comment section down bellow. Bye bye
