Annette, I believe everyone should send thank you notes after a wedding, especially. I would imagine they had registered at one or two stores, so their attendees who went to the store and bought something on their list need to be thanked. We went to a wedding last summer (2014), and just last month we got a thank you note and an apology for being so late, but this year they were both working on their Master's Degrees, so they have been busy, but they wanted us to know our gift hadn't been forgotten. And I think that was neat.
