One or Two?

One of my colleague told me that parents who opt for having only one child are selfish. I ask why. He said that well it's selfish because the kid would not have any playmates and would grow up as a lonely child and to face the world alone after the parents are gone. I never thought of it that way. 'but it could be because people can't afford more than one kid these day' I tried to explain. He said well that is just nonsense because people of our parents generation used to have more than two children and they did just fine. And we are supposedly better off now comparatively. 'but people also marry late these days, hence it could also be a fertility issue' I said. His answer is simply why wait. I do know some people who were so sure they would not have kids...ever. But accidents happen and they bite on their own words later on. And then there is another woman who is also so sure she would not ever have kids. Simply because they are annoying. Really? Is that really a good enough reason? I wonder if it is something that needs reasoning anymore. Why would someone try to justify to bunch of nobodies like us, unless she is really only trying to justify her own self. It is hard enough to decide on having a child at all, let alone having one or two. I say, it is all in god's will. Why fret?
