Tip of the month: Imperatives
We can use an imperative to tell someone to do something, e.g. Wait for me. This is OK between friends, but don't use the imperative when speaking to your boss or teacher. And don't use it to ask a big favour. We say Could you wait a moment, please? and Would you mind lending me some money? It is polite to put a request in question form.
