i'm a kid and proud of it

I don't really understand why people are all into being an adult. Because being an adult doesn't seem nearly as fun as being a kid.
Today we went to the country club for this nice Christmas brunch and ornament-making. And Santa was there as well.
I was probably the only 17 year old at this brunch, and I was definitely the only one going to see Santa as well.
But you know what? Who puts age limits on fun? I think that kids have the most fun on Christmas because they are captivated by the magic and happiness of Christmas, while teenagers sort of grow out of those things. And just because you are not in elementary school anymore doesn't mean you can't enjoy things like Easter egg hunts, Halloween trick or treating, and Santa, the way you did when you were a kid.
At this rate, I'll probably be trick or treating until I am at least 35. And I will never deny myself the joy that comes from childhood wonders.
I guess people think it is too cool to engage in childish activities that will make you seem like a fool. But you shouldn't listen to what other people think if it makes you happy.
