People who choose not to have children and are openly "childfree" often are looked at strangely by the parents and "pro-natalists" who dominate our culture and society. It is ingrained into our minds from an early age that having kids eventually is something all people do, or should at least want to do. So to think differently, to choose a different path in life, means being confronted with frequent questions and challenges from others.
It can be very frustrating to be a childfree person and to be constantly confronted with people arguing against that choice, or questioning one's motivations. Here I've collected some of the most frequently heard "bingo"s (reasons to have children) childfree people receive on a regular basis, but also ways to respond to them and rebuke the questioner. Hopefully this may help those who are childfree deal with those who find it difficult to accept their choices. And also, hopefully it will help other people open up their minds to other ways of life and being more tolerant/understanding toward them.
