Cách sử dụng
The expression "not know where to look" is typically used when someone is in a situation where they feel very embarrassed or uncomfortable. For instance, if someone sang the wrong lyrics to a song in front of a large audience, they might feel so embarrassed that they wouldn't know where to look because they wouldn't want anyone to see their face. The expression can also be used in situations where someone is overwhelmed or unable to decide what to do next.
