F.U.N.

Fun? What is fun? Fun is when you... fun is. Let me just sing it for you:
F is for friends who do stuff together.
U is for you and me.
N is for anywhere, and anytime at all, down here in the deep blue sea.

Now, if you're cynical and evil:
F is for fire that burns down the whole town
U is for uranium bombs
N is for no survivors, when you-!

Fun is when you're not obligated to do what you're doing. Fun is when you don't remember anything important. Fun is when all the problems seemed to have slipped your mind. Fun is that feeling you get when you realize it's after school on a Friday. Fun is when joy and excitement take over. Fun is the lack of judgment when doing things. Fun is when your parents leave you at home for the evening and blasting music while dancing in your underwear is the only option. Fun is hanging out with people you actually like. Fun is when a substitute teacher takes over. Fun is when old people don't awkwardly talk to you. Fun is that moment when you realize that you have money in your pocket. Fun is when you realize that you don't have homework. Fun is the moment you come to conclusion that your life is your life, and it's important to live life the way you want to live it, not how others would want to live it.
