What do you think of them?
My hubby is an only child and I have one brother. He's married to a woman that we like, and that's good with our kids, but they have decided they never want to have kids of their own. We asked why and they said they like their lives as they are and have never wanted kids. I had no idea my brother felt that way.
Is it just me that finds this kind of selfish? I can't put my finger on why, but it just nags at me that it seems selfish of them.
