That’s an interesting question. Allow me to explain my personal views by shortly mentioning the following points: Firstly, I believe that fathers all over the world want someone to carry their name into the future. For example, in many western countries it is customary for a boy to receive his grandfather’s name. A second reason that I could mention is that parents worry about what will happen to them after they had retired. They feel that when they have a son he would be able to provide for them in future.
