How about "in the evening" or "in the morning" as a one-time event? I understand that if one does something every evening the term is "le soir" (Tu ne lis que le soir). But what if I'm referring to a specific evening, for example: On est partis tôt et on est arrivés à la maison (in the evening). While I'm asking, how would one modify that to express "early in the evening."
