How to say it...

Jak powiedzieć "Nie będzie mnie przez dwie godziny"?

I won't be for two hours???

Thanks in advance.

I'll be back in two hours - I should think:)

...or: I will be off for two hours :)

albo 'away'
:-))

... ale i tak ze wszystkich podanych wersji "I won't be for two hours" brzmi najfajniej :)

"I won't be for two hours" jest źle

I won't be for two hours? Not doing what exactly?
I won't be (thinking, dancing or eating etc ) for two hours
'I will not be IN for two hours' might be better.

>I won't be for two hours?

This must be a butterfly speaking :-)
I won't be for two hours = I'm going to live longer than that.
