RSVP

Why even bother putting RSVP on invitations anymore? It is just a waste of time and ink! It is now 2 days before Shauna's shower/brunch and I need her to call people to see if they are coming or not so that I know how much food to prepare so everyone has enough to eat. I know people are busy and I have been guilty of the not RSVPing in the past. But I am really learning a lot in planning this wedding and I sincerely apologize for any invite I did not respond to in the past in a timely manner. From now on I will do so the second I get an invite
