After hearing the truth, I can understand that. Why am I no father listed on the birth certificate. I was not hurt, but I love my father more than ever. I was impressed that even though this is not the real father, but I was raised well. And regret that I sometimes make absurd arguments father and his father was disappointed in me. Those feelings become the driving force for me to study more. Behave well as the undisputed father taught. The father is willing to work hard. I want my father proud and happy time together.
