My own poem about childhood

When I was a child, happiness was like a bicycle, with my father in front and me at the back.

When I grow up, happiness is like a car, with me in the front and my father at the back.

When I was a child, happiness was holding her hand, with me in front and her behind.

When I grow up, happiness is the old ticket to her, with me at the end, She's over there.
