sad story

My dad left my mom and me when i was 3. He had so many kids that he didn't pay child support for and all with different women. If he was in a moment of need to pay off bills or about to die i walk the other direction and ignore it. Why should i care he never did anything for me. It may be a choice that is considered a sin but i would be able to bare it because i have a new dad who just proposed to my mom who is very happy. He may be a little mean but he provides the family, is there to support me for sports and school so grow up to become a respectful adult and make good choices.
