I recently had a chance to really sit down and talk with a new co-worker who is turning into a great friend - I came over to her house to help her move some furniture the weekend her husband was out of town, and we talked about all kinds of things for several hours.
In the course of conversation, she mentioned the "surgery" she had undergone last year was to get her tubes tied, since she and her husband didn't want kids and had had two pregnancy scares. (She had mentioned the surgery in vague terms when we first met, but this was the first time we really had an in-depth conversation.) I replied with something about how kids aren't for everyone and it must be nice to get [worry about pregnancy] off her mind.
Now, DH and I are planning to have children in the next few years, and she knows this. There are also two couples in our mutual social circle who are pregnant, a few who already have kids, and another couple who have infertility issues who desperately want to become pregnant. Apparently kids must be a big topic of conversation most of the time, because she just gave me a stunned look and said "But you want to have kids!" Now, thanks to EHell, I had a pretty good idea how to talk to someone who was childfree by choice, and she was just shocked. "You wouldn't believe how many people have looked down on me for this [the surgery]."
That makes me sad - yes, I do want children, and I wouldn't have made her choice, but why does ANYONE think they have the right to tell her she should or shouldn't produce offspring?
