My wife and I made a conscious decision not to have children. We both came from large families of very modest means and we wanted to live a simpler life dedicated to one another. It might seem odd, but it made sense to us at the time and still does. When we wanted kids around, we borrowed them from our relatives and gave their parents an evening or a weekend to spend with each other. Our house has always been well-stocked with puzzles and non-electronic games, and kids are fascinated by astronomy, which I have been engaged in for decades. When we had ferrets, they were a real draw for the kids too, and some of the kids drove me to distraction mining my music collection. Some of my favorite old albums were their favorites too, including Simon and Garfunkel, Hendrix, early Jackson Browne, Bonnie Raitt... My wife and I never had kids, but we've helped raise quite a few.
