I was thrown a shower on May 19th. We let the shower guests know that day that we were having to postpone the wedding. We found out the week before that the church was double booked. With all the change of date notices, new invitations and basically replanning the wedding, AND moving, my thank you notes got burried in a tote bag. I just found them! Do I need to stick an apology note for mailing them so late? Or call everyone and apologize? Or just let it go?
