I just got born. There's nothing I can do. Maybe "nothing" is such an appropriate word for an age 0.
A year passed. There's still nothing I can do. I haven't changed. Maybe I am to retain my purity? Yet people started liking me so much. I was happy.
Another year passed. Now I just realized something. Many things in this world can be cut in half. To identical pieces. Maybe that's because I am 2, "half" being its reciprocal?
Yet another year passed. Since this time, something has been wrong. Before then, I retained my purity. And I was normal by myself. But since then, a half of me became abnormal.
Yet another year passed. There came another abnormality. Besides the retaining half-abnormality, 5/6 of me gained another kind of abnormality.
Yet another year passed. The 5/6-abnormality went away. But people stopped liking me. I was sad.
Yet another year passed. Beside the half-abnormality, I felt like... "I am doubly inside me." Sorry, I couldn't find better words.
Yet another year passed. That "doubly inside me" thingy went away. Yet the half-abnormality remains today.
What am I? I'm so sad.
