Let bygones be bygones的意思

"Let bygones be bygones" is an English idiom that means to forgive and forget past mistakes or offenses, and not to hold grudges. The phrase "bygones" refers to things that happened in the past, and the idea is to treat those things as if they never happened, and move forward without resentment or anger.

The phrase is often used as a suggestion or a plea, especially when two parties have been in conflict or when there has been a misunderstanding or disagreement. It suggests that both sides should put the past behind them and start fresh, without the burden of past grievances.

Here's an example of how the phrase might be used in a conversation:

Person A: I'm really sorry for what happened last week. I shouldn't have spoken to you that way. Person B: I accept your apology. Let bygones be bygones.

In this example, Person B is saying that they are willing to forgive and forget the past incident, and move on with a clean slate.
