The boy said, “Daddy, you’re crying. Are you hurt?”
“Yes, I am.”
“Where? I can’t see it.”
“In my heart and in my head.”
“Why?”
“Because Grandpa, my father, died and I miss him.”
For the first time the boy knew a pain beyond the physical scrape of a grazed knee, the sting of Dettol and the salve of attention.
In the awkwardness of facing human pain he saw the wounded soul seeping out from behind an imaginary Band-Aid; a too small covering for a gaping wound.
He leaned forward and kissed his father’s forehead.
