As did I. I have a feeling that when it comes to getting presents and being an adult, most people would've already expected you to get your own things. And then there's also the inevitable fact that even the closest of friends can grow apart when you get older, so even if you and your friends would've liked to have a Christmas party at your house, it would seem highly unlikely if they also have their own families to visit, or if they've relocated. And then if you're also growing apart from your family, or weren't that close to them to begin with, it would be sort of like going through the motions, even if you're still okay with them.
For me though, I think an ideal Christmas party would be close friends and family that you have an excellent rapport with at your home for that night. If I also had the means, I would definitely purchase gifts for close friends as well. I believe that it is possible to have close friends, or even friends and acquaintances that you can hold in regards as high as if they were blood relatives, as a reason to give them presents if you have the means, but that's just me. As somebody that's given some presents here and there on Christmas and birthdays, it really does give me a very good feeling.
Monetary reasons aside, which are very understandable, it seems like one of the best things close friends can do for each other on birthdays and Christmas. I also like the idea of knowing what to get, like, "Is there anything I can afford, that you didn't get around to purchasing?" I think when the time comes, I just might be the kind of person to put money aside for the holidays to give presents like that. As you can tell, I still didn't outgrow the gift-giving spirit of birthdays and Christmas.
Oh, and sorry for the rather late replay. I just wanted to think about it for a moment before posting. I'm all for Christmas being joyous and fun, and if not for the presents, close friends, and family, definitely for the food.
