Blessing in disguise

Father and son were sitting on a peaceful shore when the boy began to sob.
Pulling him closer the father said, “The truth is hard for you, I know. Do you regret having me as your father?”
“Not ever.” The boy kissed his dad. “But it feels bad to be an unwanted abandoned child. Is congenital blindness my fault?”
“You weren’t unwanted. Its just that I needed you more than them.” The father quipped. “No girl would marry a crippled man like me. How would I become a father then. Our imperfections is a blessing son. ” The father sighed.
