I'm meeting / I'll meet

I'm meeting / I'll meet
 

-Choose the correct form

A: What are you up tonight?
B: I'm meeting / I'll meet some friends.

I think the correct one is the first one (I'm meeting), or at least the most common, but I'm not sure why... maybe because the second choise has a space for doubt and the first one is surely happening and, in conclusion, you need more context to choose one? The teacher said, to make it simplier for us, that both are correct, but if you go on deeper on them it's not really like that. I'll appreciate an explanation.

Thanks, goodbye.

Your teacher is right they are both correct. (you can also say I going to meet some friends) The second choice would be used less however.

The second choice may be correct, but it doesn't sound right to me. "I'm meeting some friends" or "I'm going to meet some friends" are the best choices. Although "I'm meeting some friends" sounds a little awkward to me. I think I would either say "I'm meeting up with some friends" (as in I'm hanging out with some friends) or "I'm meeting some friends for dinner/at the movies/etc.

As for why the first choice is correct (& why the second choice sounds awkward), I think it may be similar to saying "te llamo" when you are going to call someone later that day, which would technically be in the future, but you use the present tense because it's near future?? ..."te llamaré" would sound awkward, right?
:twocents:

(For the record, I'm no grammar/english expert by any means...I just speak it!! :D)

Context changes everything. Where "I'm meeting some friends is more common, here's a couple of examples in which I'll meet some friends sounds OK:
A worried mother may ask, "What are you doing tonite? Are you going out alone?

The rebellious teenage daughter may answer, " I'll meet some friends" (with the accent on the I'll)
or" Don't worry about about me. I'll meet some friends"

another example:
"I don't want to go to the party tomorrow night"
"Why?"
"I don't know anyone there"
"Don't worry you'll meet some friends"
or Don't worry you'll meet some new friends"
'

The question is in the present tense, so an answer in the present tense is more natural. The real question is why A asks "What are you up to tonight?" rather than "What will you do tonight?"

:hmm:I think the latter is more what you'd ask if you're worried about someone because of circumstances which can't be fixed until tomorrow. But I can't give you a rule for why.

In your question, the second choice is the better.

What're you tonight.

I'm meeting any friends in the party.
Because in the first one, you still will know to the friends, I mean, yours ones.

I hope that you can understand me.

Thanks all for your answers, now I understand it better.
