While my husband and I were completing thank you cards for our wedding, my husband recalled a wedding he attended 4 years ago.
Instead of thank you cards, the Groom sent out a mass text message to his guests the day after his wedding, stating something along the lines of, “Thanks everyone for coming out, it was great seeing you.”
No formal thank you cards were ever sent out. Just that text message. I am not sure how people who do not own a cell phone were thanked. 0328-14
If the bride and groom has circulated through the guests during the reception thanking them in person for coming, there would be no need for an impersonal text message blasted to everyone.
As for the lack of a thank you note, expect to see more of this kind of belief that people are entitled to receive wedding gifts and that guests have an obligation to endow them with materials goods. Kings and queens don’t bow to plebeian expressions of gratitude when their inferiors bestow upon them what they view as rightly theirs in the first place.
