@Luvsmyfam @I agree with you that sending a thank you card is proper etiquette. Today it really seems to be a hit or miss if you ever receive one. I would be annoyed but it's one of those things that you just have to move past. Going forward, you know to not put much effort into a future gift for this person.
I have to mention my nephew and his wife. They came to my house last Christmas and I gave them a small combined gift plus an inexpensive toy for their two year old little boy.
I don't know who of the two wrote out and sent the thank you card, but in January I received one from them. I was thanked for having them over ( I usually do), for the gifts and just in general acknowledging the fact that I put a lot of effort into having people over for the holiday! That was such a pleasant surprise!
