I expected to have my wedding invitations ready by Valentines Day, and they were. All we had to do was seal them and mail them. Unfortunately, my father had a heart attack and died that day. I just got back around to organizing everything again today, and my RSVP's state "Kindly reply by March 7".. We were still going to mail them, instead of paying to have new ones made, but I thought it would be considerate to put a letter in each one apologizing for the inconvenience and asking that they have their RSVP's in the mail by April 7th. We're not getting married until June 14th, but we wanted to know the numbers early for catering and venue purposes. How do I word this letter.. "Due to unfortunate circumstances.." etc. etc. I just don't know how to start this letter without it bogging down the invitation or being too personal.
