What RSVP means
RSVP is French for “please reply”, and that is all it asks. The polite line at the bottom of a paper invitation becomes, in a digital one, a short form at the end of the page: coming or not, how many people, which menu, a dietary note if there is one, a message for you if they feel like it. No account, no app, not even a newer phone — it opens from the link they got on WhatsApp, for grandchildren and grandparents alike.
