Cách sử dụng
The expression "grow up" is used when someone is behaving in a childlike or immature way and needs to act more like an adult. It can be used in various situations, such as when someone is throwing a tantrum, not taking responsibility for their actions, or not acting appropriately in a certain situation. For example, if a friend is complaining constantly about small things, you might say "you need to grow up and learn to deal with the little problems in life." It's important to note that this phrase can be seen as harsh, so it's best to use it carefully and in a constructive way.
