I'm having lunch

[Rosario]

Hello everybody,

When I walked among some friends to have lunch, I said to them as below sentence:

I’m having lunch.

Is that correct?

Thanks in advance.

I'm not sure. What is your intention? If you are walking with friends on the way to lunch, why would you say this?

I meant, I walked alone through office’s visited room and there are some friends who still sitting there, so I just said to them “ I’m having lunch now”. Because it's lunch time and I went home for lunch.

[Mister Micawber]

Yes, that's fine-- or 'I'm going for lunch now', which is more common.

Thank you so much Mr.Micawber.

There are some foreign consultants in the office, so I have to practice my English with them.
