Invisible Love is a book I read.

Blind people can't see anything. They can't see the blue sky. They can't see the green grass. They can't see the tall trees. However, he could see the endless world clearly in his heart.

When I first started reading Invisible Love, I was worried that the boy couldn't see at all. How could he hit the bottle with a slingshot? I couldn't help thinking. The little boy and his mother played slingshot together. His mother handed the stone to him again and again. The boy put the stone in the leather case again and again, and then played it out. No matter how tired he was, the boy and his mother never stopped until there was a clear sound of the bottle breaking. I don't know how many slingshots this boy has fired, but it must have been thousands! I don't know how the blind boy got hit. I hold a puzzled curiosity to ask my mother, mother said the boy has a persistent heart; I asked my father, father said it is mother's love to support the boy so persistent down. I thought about it carefully and finally understood that the blind boy could hit the bottle because he had a persistent heart and his mother's silent love, which created another bright sky for him.

Even if the son is invisible, the mother will accompany him until dark; even if love is invisible, we still believe in it forever. Love can create miracles.
