OKAY...Lets get serious for a little bit. Its driving me crazy. "Brothers and sister I have none,but this mans father is my fathers son" Who is it? There is an answer but I can;t figure it out.
Never mind guys I figured it out. So have fun. HaHaHa
My thinking leads me to say that the answer is "himself".
Hope you are having a great day.
Your son and you are a man.
