By about a week before the big day, you will have received less than half of your invitation response cards. Panic sets in when it occurs to you that everyone invited will actually show up. You couldn't have made it easier for your guests. You have included a card that had boxes for 'will attend' or 'will not attend.' You included a pre-addressed, stamped envelope. How inconvenient could it be for them simply to check it off and drop it in in a mailbox? Very inconvenient. You, evil bride-to-be, are confronting two basic human fears. A terror of correspondence and the dread of decision-making.
