Analysis of the Absent Father

Unwanted

She said she was pregnant. Neither of us had planned on that. We had taken precautions; nevertheless, here we were in the doctor's office.

She' did not want the baby. We discussed abortion, we discussed adoption. Neither one seemed to be the best decision. We had created a life and it was part of us, but it interfered with our lives as hunters. The idea of a stranger raising my child was upsetting; it would not be easy for most people to understand the nature of the child whose DNA came from two talented hunters. He would be active, inquisitive and very strong-willed. Still at it was a possibility. Neither I nor the mother had the time or desire to cope with the child. I contacted my cousin. She wanted the baby. It wasn't easy way out and I grabbed it. I offered the mother a substantial amount of jenis to carry the baby to term. She readily agreed.

After the birth of the child, we went our separate ways. I carried the baby halfway around the world and left him at Whale Island. I named him Gon. I do not know what whim prompted me to do so, but there it was.

I left and walked away, back to my own life. Later, after I had created the video-game Greed Island; I sent him a small box with a memory card. I guess I was proud of the game. Maybe it was my one contribution to him as a parent, a way to train to become a stronger hunter. Maybe, it was because I thought of him occasionally.

It did not really matter. In the end, we were still two separate people, not a family and I honestly had no desire to see him or pursue a relationship with him.

Gon was simply an accident and I left before I was held responsible for the mess and made to take care of it.
