What's the most thoughtful gift someone has given you?

With Christmas coming up, I guess Kwanza or whatever the fuck that Jew holiday is too, I was thinking about the whole gift-giving season and was wondering what's the most thoughtful gift someone has given you (or possibly the most thoughtful gift you have given to someone else, though I don't know how you would know it was unless they told you, or you had some preconceived notion on how it would be a really good one)? Maybe also who gave you the gift, and why it was a good match for you to get that certain gift too.

I don't even really celebrate my birthday anymore and the last time I got a Christmas present, who knows when, so I don't remember the last time I was ever given a really good, thoughtful gift. I only remember receiving gifts of money, but that doesn't take any thought and is fucking half-assed and lame, or else I would share one with you guys. I think I have given thoughtful gifts before, but damned if I know.

Edit: Topic implies only the most bestest gift, but if you have more than one experience to share, feel free to pass it around. And Merry Christmas to all you guys.

Jam it back in, in the dark.
