Can we also write "Jsme už tam" or does that sound unnatural in Czech?
It is accepted.
Thank you VladaFu!
What's wrong with "We are there yet"
That means you are still there, you haven't left yet. Not that you have already arrived.
So - when there is a question mark it means - "are we there yet?" - same phrase????
Yes. I suggest to limit the number of your questionmarks. It may look rude.
