The fire is dying down, it's getting colder, and you have an early day tomorrow. Piling together in the tent with your mostly-inebriated friends, you get comfortable in your sleeping bag but can't quite seem to drift off to sleep. You're not the only one. Your friend, wrapped up in his own sleeping bag next to you, is clearly restless. You quietly observe him as he writhes around, searching for a comfortable position, giving long drown out sighs of defeat. Soon, he rolls over and meets your slightly open eyes and asks you... "Are you still up?"
