Like a cake in the oven after a loud crash, my heart fell

I was sitting in the third row, second seat from the back when she walked through the door. She had short brown hair, wore no-name blue jeans, no-name white tennis shoes, and a brown sweater. She handed the slip of paper to the algebra teacher. The algebra teacher told her to sit in the third seat of the second row. She had freckles dotting her nose and upper cheeks. She had brown eyes and a pretty smile. My heart fell.

Nine months later she invited me to her hosue for the afternoon. She was about to leave - headed back to Brazil with her parents. We played chess. I was a nerdy little kid, I didn't know anything about dames. Afterward, I walked home. I didn't even look back. I should have looked back. My heart fell.

Twenty-seven years later... where is my heart?
