je dois partir
I must go to the station at three o'clock.
Je dois aller à la gare à trois heures.
I must go now, but I'll come back.
Je dois partir maintenant, mais je reviendrai.
Either you or I must go in his place.
L'un de nous deux doit aller à sa place.
I appreciate your visiting, but I must go.
J'apprécie votre visite, mais je dois partir.
