If you have nieces and nephews, your genes are being carried into the future! My 3-year-old niece is practically my spitting image. Everybody says so. She came to my house and saw a picture of me at her age and exclaimed, "this is me!" And I am frequently mistaken for my aunt's daughter. You may be childless, but you belong to a family and a bloodline. If you don't have the kids, for whatever reason, somebody in the family will. We all live on in the hearts and minds of people who love us.
What a beautiful thought.
Nice thinking.
What strikes me about the author is that he isn't able to discuss these musings with friends & family. What on earth possessed him to write this pitiful article. Reads like something you would discuss with a shrink (if you have no friends or family).
As Tom Daschle would say, "I am saddened".
