I was watching TV today and I noticed a common phrase that I guess you didn't learn in school. I wrote it down because I wanted to remember to teach it to you. I think it's really useful. So many schools teach old stuff but I really want to teach the popular kind of English that you can actually use with native English speakers. Here it is below:
Sleep on it:
In spoken English, if someone tells their friend to, "sleep on it", it means that they should really think carefully before making a decision. This is used when someone has a big and important decision in life to make. The idea is that you should go to sleep and make a final decision the next day so you don't make an emotional decision.
Here is an example of how to use this:
Rina: I'm thinking about buying a new Ipad but it's kind of expensive and I'm not really sure if I really need it or not. Do you think I should get one?
Riyaj:I think you shouldsleep on it. If you still want one tomorrow morning then just buy it.
