on us; to us
Los blancos pueden ayudarnos, pero no se nos pueden unir.
White people can help us, but they cannot join us.
— Malcolm X (1992)
And do what is asked of us.
We've run out of money.
Venga, seguro que se nos ocurre algo.
Come on, I'm sure we can think of something.
— Love Actually (2003)
We lost the keys.
