I'll be 16 on December 26th. I've gotten the same question from all sorts of people on how exactly we celebrate my birthday since it's the day after Christmas so I'll go ahead and mention it so it doesn't pop up later.
I get to choose how exactly my birthday goes and I normally just tell them to give me a bunch of money so that I can go out and spend it on what I want to purchase. They don't take it personally (I can't have any parties since it's a holiday) and they don't say that I just don't want them to purchase gifts for me. They like that idea better than having to hide everything because this house has so much storage that the gifts are going to get lost.
