Don’t cry over spilled milk

The internet slang term “Don’t cry over spilled milk” means that one should not get upset or dwell on past mistakes or unfortunate events that cannot be changed or undone. It encourages people to move on instead of wasting time and energy lamenting over something that has already happened.

Examples:

1. Person A: I accidentally deleted all my important files from my computer! I’m so mad at myself!
Person B: Hey, don’t cry over spilled milk. Instead, try to recover or find a solution for it.
2. Person A: I missed the train and now I’m going to be late for work. I can’t stop thinking about it.
Person B: Don’t cry over spilled milk. It’s out of your control now. Just focus on being productive once you arrive.
