I just got back from this huge group sleepover my theater class had.
Strangest thing ever, but I wouldn't have missed it for the world.
Playing apples to apples and leading the discussion into the realm of David Tennant's attractiveness. Taking pictures as the guys figure out new gay sex positions without even taking their clothes off. The phrase "We're all theater students, we're all mostly straight, what's the problem?". Wearing Doctor Who pyjamas and participating in an orgy (3 or more people with some limbs touching with their shoes off). Staying up talking in the moonlight until 3 am, when you realize it's snowing and go outside without a jacket, only to spin around, remark it looks just like the Ood Sphere, and go back indoors, leaving your classmates to perform an improvised musical number in the middle of the street. Snuggling down into your sleeping bag when everyone is finally ready to go to bed, sharing your pillow with a classmate, and being surrounded on all sides by sleepy, murmuring people. Realizing it's 4 am, and frantically shaking your sleeping classmate awake so he can tell the 4 am joke: "A guy walks into a bar. The bartender says 'sorry mate you can't come in here'. The guy says 'why not?' The bartender says 'because I'm an alien.'", and laughing your head off thinking it's the funniest thing in the world, because everything is funny between 4 and 4.30 am. Waking up at half past seven when you've only gotten three hours of sleep, noticing that the classmate you're sharing your pillow with is still asleep, but the guy in the grade above you sleeping next to her has just woken up, and exchanging a drowsy 'good morning'.
If that doesn't define happiness, then what does?
