Cách sử dụng
The expression "it’s/that’s not my problem" is used when someone wants to politely tell another person that they cannot help them with their issue. It is often used when someone is asking for help or assistance with something that the speaker is not responsible for, or that is not their concern. For example, if someone asks you to fix a problem with their computer, but you are not a computer expert, you might say, "Sorry, that’s not my problem." It is important to use this expression in a polite manner, as it can come off as dismissive or unhelpful if used incorrectly.
