Don’t cry over spilled milk
Basically, it means that you shouldn’t get upset or dwell on something that has already happened and cannot be changed. It’s like when you accidentally spill milk on the floor, there’s no point in crying about it because the milk is already spilled and you can’t undo it. Instead, it’s better to focus on finding a solution or moving forward. The idiom is often used to remind people to let go of past mistakes or regrets and not waste time and energy on things that can’t be changed.
In a broader sense, the idiom is used to remind us not to dwell on past mistakes or unfortunate events. It’s about accepting that what’s done is done and focusing on finding a solution or making the best of the situation. We all make mistakes or encounter setbacks in life, but it’s important to keep a positive attitude and learn from those experiences. Instead of wasting time and energy feeling sorry for ourselves, it’s better to use that energy to find a way to fix the problem or prevent it from happening again in the future.
