Cách sử dụng
The expression "old enough to know better" is used when someone does something that is considered silly or wrong, but they should have known better because they are old enough and should have learned from their past experiences. For example, if a teenager breaks a rule they have been told repeatedly, they might be told that they are "old enough to know better". It is a way of reminding someone that they should have made a better decision based on their age and experience.
