One day, as we were walking by the riverside, I asked my son, “What do you want to become someday, honey?”

He did not respond. He is tiptoeing on the whitish sand. I think he did not hear what I said, so I slightly squeezed his hand, which was holding mine to get his attention. He looked up at me, wearing an innocent eyes. I smiled at him and asked the same question again.

“What do you wanna become when you grow up?”

My son is eight years...
