Cách sử dụng
When someone says "learn your lesson", it means that they want you to understand that you made a mistake or did something wrong, and that you should not repeat that mistake in the future. For example, if you forget to do your homework and get a bad grade, your teacher might say "I hope you learned your lesson and remember to always do your homework in the future". This expression is usually used when something negative happens and the person wants to use it as a teaching moment for you to improve your behavior.
