Cách sử dụng
The phrase "when you’ve seen, heard, etc. one, you’ve seen, heard, etc. them all" means that something is not unique or interesting because you have already experienced it before. It is often used to describe situations or experiences that are repetitive or similar. For example, if someone says "I don't like going to chain restaurants, they're all the same," they mean that they have been to one chain restaurant and found it unexciting, therefore they believe all chain restaurants will be the same.
