Cách sử dụng
The expression "creep up on" means to approach someone or something quietly and slowly without being noticed, until you are very close to them. It can also mean to gradually become more noticeable or significant over time, as if sneaking up on you. This expression is commonly used in situations where someone or something is either trying to surprise or catch you off guard, or when something happens gradually without you realizing it until it's too late. For example, you might say "I didn't hear him coming, he just crept up on me," or "I didn't notice how late it was getting, it just crept up on me."
