When we arrived (:

or the movie- Are We There Yet?

When we call. or When do we call ( depends on the tone)

* Edit: I was wrong. I was thinking of Llamamos in my head. It is actually When do we arrive or When we arrive.

llegar = to reach a destination.

cuando llegamos = when we got [there/here/...]

When we arrive

When do we arrive?
