I'm not harboring a long post about this at the moment, but it seems like a good time to start this thread. This is intended as an exploration of people's philosophy and logistics; like the atheist thread, debating the existence of childfree people or their "appropriate" role in society is best left to some other thread.
How long have you been childfree? Are you single or attached? How has it affected your relationships with family, friends, etc.? Do you tell people or just leave well enough alone?
