No me disgusta que salgas con Lupita; al contrario, me parece que hacen buena pareja.I don't disapprove of you going out with Lupita. Quite the opposite, I think you make a lovely couple.
Disculpa que me presente así sin llamar. - Al contrario, estás en tu casa.I'm sorry for coming by without calling first. - Quite the contrary, make yourself at home.
