The risk I took was calculated, but man, I am bad at math

When I was a little kid my mother told me not to stare into the sun. So once when I was six, I did. At first the brightness was overwhelming, but I had seen that before. I kept looking, forcing myself not to blink, and then the brightness began to dissolve. My pupils shrunk to pinholes and everything came into focus and for a moment I understood. The doctors didn't know if my eyes would ever heal. I was terrified, alone in that darkness. Slowly daylight crept in through the bandages, and I could see, but something else had changed inside of me. That day I had my first headache.
