How would you use this sentence in conversation? Would you say it while waiting for a bus or a train?
I'd more likely say "Este é o nosso" when referring to a bus/train, etc. "Este é para nós" could be a piece of paper, food or any other masculine object.
When do I use nos / nós?
Thanks for the reply. Are my following thoughts / examples correct?
They are perfect! I just had to check about preterite - I've not reached it yet ;)
