I know why you posted this, in response to a question that was asked, not complaining about your post.
But these types of statements are what I hear (not as much now that I'm older
) a lot.
My point is that even if you did pity me for whatever reason, keep it to yourself. When I'm asked (I don't just going around telling people I don't want children) all I had to say was "I don't want children" and I would get these unwanted talks about how so and so felt the same way, but then had children and how her life is so much better, etc. While I'm sure that's true for so and so, what the heck does that have to do with me?
I think it's when people feel the need to explain to me why their lives are better with children, when I didn't ask them...why are you telling me this?
And I understand other people don't experience this, but I have. Maybe it's because I'm always interacting with people that requires some amount of small talk, and the conversation naturally turns to families, etc.
