No real etiquette question here, but thought it might be fun to speculate about!
A little BG - one of my uncles, Uncle K, has always a very distant part of the family. I met him once, when I was a kid, and he said maybe two sentences to me, and that was it. He talks to my grandparents fairly often, and has come out to see the rest of the family a couple of times when I wasn't able to make it.
Guess who I got a Christmas card from this year?! You guessed it, my Uncle K and his family. I don't know that I'd consider that too odd, except that no one else in my family got a card from him. Not my parents, aunts, uncles, or grandparents. I am, apparently, the only one in the family that he sent a card to. It's so weird! I have no idea why he would send me a card and nobody else. I think my grandparents were even hurt that he would send me a card and not them.
Any ideas why I would be the happy recipient, and not any of the people in my family he's closer to (like his parents or siblings)?
