I have been married for 17 years and have no kids. I tried to talk myself into it for a while, but decided I really prefer the world of grown-ups. Children don't make interesting conversation and taking care of my husband is exhausting enough. I tend to have a lot of anxiety around children and I feel like they can smell my fear. Plus, the idea of having a child living in the house with us really freaks me out--like a guest that won't leave.
It's crazy how people react--so tactless. When I say I don't have kids, people act like I've done something wrong. How do they know I don't have a medical problem that prevents me from having children? Actually, maybe I do--Asperger's.
In any event, I'm happy with my CHOICE. As my husband and I enjoy a delicious Martini and some nice music & conversation in the evening we can hear the ill-tempered brat next door screaming and carrying-on (awake way past his bedtime, as usual). We often reflect on how lucky we are not to have to put up with that kind of chaos.
