Cách sử dụng
The word "hey" is a casual greeting that is used to get someone's attention or to say hello. It's often used in informal situations, like with friends or family. For example, you might say "hey" to greet someone you know when they walk into a room. It's important to note that while "hey" is a common greeting, it's not appropriate to use in every situation. In formal settings, like a job interview or meeting, it's better to use more formal language like "hello" or "Good morning/afternoon/evening". Also, it's best to avoid using "hey" with people you don't know or in professional situations, as it may come across as too informal or disrespectful.
