Dear Austin parker,
We would like to tell you that Josef and I are rethinking our plans of getting married. You may be completely stunned by this, but we just felt it would be wise to hold the wedding off until such time that we are fully prepared for a lifelong commitment.
We sincerely apologize for any inconvenience that this might put you through.
