I sent 2 items as a wedding gift off the couple's registry, and they were to be delivered to the address on file. I typed in a personal note with our full names on the gift enclosure option of the order. I ordered these in Feb, and I got a few emails from the store saying they were back ordered and I believe they were ultimately delivered in late March. (Then in April I was invited to a bridal shower which I could not attend, but I mailed a shower gift to one of their relatives for her to take to the shower. I know the shower gift was received b/c several of my friends who were in attendance told me what a big hit it was, plus I received a thank you note from the bride-to-be specifically naming the items in the shower gift). But back to the wedding gifts, I do not care about a thank you note but would like to be sure that they received them and that they know they are from us. I know sometimes things can get misdelivered or stolen off a porch, or sometimes the stores forget to include the gift enclosure card noting who it is from. The couple is young enough for me to be their mother so it's not like they are peers or close friends that I communicate with, so it would be out of the blue for me to contact them to ask them. The groom is the son of some of our long time friends, but if I were to ask him or his mom, I am soooo afraid that they will be embarrassed about not sending a thank you note b/c I know both families have impeccable manners. I feel like it's most likely that it was delivered to the right house, and hopefully the store did note who it was from, but it was a fairly expensive gift and I would love to be sure they really got it and that they know who it is from, and in the alternative I would want to f/u w/the store in the unlikely event that the couple says the gifts were not delivered to them. But the last thing I want is to embarrass them or do anything that could be considered rude. Does anyone know the proper etiquitte on this?
