Os vais or vais

Question

I got as an answer:

Nope! Study the explanation. Because the action is focused on the destination, you will use the ir form for nosotros which is vais.

When I added Os vais to the blank in the question:

Are you going with us? - ¿___ con nosotros

I do not seem to find any destination here. Did I miss something? Thanks very much Paamon

Answer 1

Thanks

Answer 2

That is Spanis of Spain.

Spanish of Latinoamerica and the rest of the world is ¿Te vas con nosotros?

I recommend you, Spanish of latinamerica.

Thanks. But it is in plural so should it be "vais con nosotros" , but why ir and not irse although there is no definite destination ? (you can find the Spanishdict explanation here http://www.spanishdict.com/topics/show/108) Thanks again - paamonim, Mar 24, 2012
