post-exam high

It's summer. You're sixteen. You've just finished months (nay, years) of preparation for and taking exams. You have parties to go to, places to visit, friends to see. Your babysitting earnings are burning a hole in your pocket. You have perfected the art of walking high heels without falling over/breaking your ankle (so far). You have new ways with toe-nail decoration to show off. Why wouldn't you buy them?
