I'm a woman in my mid-40s. I do not have children and have simply never wanted children.
I've been called selfish, shallow, and other such things. Something must be wrong with me. No man will ever marry me if I won't have children. I'll change my mind - on a scale of "because I'm young and stupid" to "biological clock will kick in".
None of this is true, of course.
I usually have an open mind to other people's personal choices. I rarely judge other people's personal choices. This is probably one of my few good qualities.
As a terminal procrastinator who frequently pulls all-nighters (this year I even got to two in 3 days) I was terrified (and apparently decided to never comply with any deadline anymore, but that's another story).
