Thipu, I am with you on finding this humorous. If you send regrets to a wedding, why keep inviting you to all the events of the weekend, especially if you are from out of town? Also, as I have said before, I worked in the social stationery business for 13 years, so we did a lot of wedding related invitations, and one of our biggest wonders was the rehearsal dinner having turned into a big to do. Typically, rehearsal dinners are for the HC, their parents, grandparents, and the bridal party. I remember one we did where the mother of the groom was inviting over 100 people to a fairly formal dinner for the rehearsal and we were a bit flabbergasted..almost like a pre reception.
