Okay, so really how hard is it to check a box on an RSVP card and put it back in the mail!!!!! I even went to the trouble of setting up a mail merge so they don't even have to write their own names on the card. Just check the box, put it in the self addressed, stamped envelope, and put it in the mail box. Is that really so difficult? The due date is Sunday and so far out of 143 invitations that were sent, we still have 63 that haven't come back!
