Blah, blah, blah

We printed nice colored picture invitations and sent them out to over 160 people. The invitations had a return card with I will, I will not (attend) and don't bother me again, boxes. It was addressed and stamped! We requested a return date of the 15th! To date, we've received 30 returns. What's wrong with you people, all you have to do is check a box and drop the thing in the mail. How about some feedback!
