We're going to have a housewarming party and I'm trying to put the e-invites together. Here's the problem: We're going to provide pop and food, and some beer/wine/mixers, but I know our friends and family. We can't afford to provide enough alcohol for all of those people! (They aren't lushes, OK some are, but they do enjoy their adult beverages.) So how can I tactfully say that?
