Oh man. You are right, teenage years are the worst time in Christendom to have to endure Valentine's Day. It doesn't matter how attractive/unattractive you are, almost everyone will be disappointed at some point. At least when you're little everyone is obliged to give you something, and when you're older no one gives you anything and you can peacefully not give a shit.

I remember when my Dad was dying I was away from school to visit him in the hospital in Ohio. He gave me a bunch of roses, which someone had had to go out and get for him, but it was the most meaningful thing I ever received. When I got back to school after he died, I found a bunch of Valentines in my locker, and a big balloon from one of the most popular girls in school. It was the best Valentine's Day I'd ever had, even if it was so sad. But it was nice to see that teenagers can still have hearts.
