I do not regard myself as "childless," nor will you see me running around telling people that I'm "childfull." My motherhood status shouldn't matter just because we live in a society that has told us that yes, having children is something that comes next once you're married; it's just what people do; it's imparting survival on the species; it's some sort of duty and if you don't fulfill it you're selfish and self-absorbed. Well then, so be it.
The subject of women not having kids for whatever reason has been beaten to death. I don't have 'em, don't want 'em right now and I don't know if I ever will. And that's where the story ends.
