Dear Prudence,
I have a question about RSVPs. This comes up more and more often: We invite friends to something that can only accommodate a finite number (a ticketed event, a weekend at our beach house, a dinner party at a restaurant), invitees say they want to go and will check to see if they can … and then they don’t make up their minds. The date gets closer and we don’t know if they are coming or not, and it’s getting to be too late to invite others. Is it ever OK to rescind an invitation and invite someone else? How do we politely say, “I need to know now, not a day before the event?” This happens especially often with our beach house: People say they are coming, then change their plans at the last minute or come for only one night of a holiday weekend, for example, when we could have invited others who would be thrilled to come.
—No, Seriously, RSVP
