I don't understand why some people do not ever want to have children?
I had the sterilization operation at 20 years of age, just before I married Charlie. I KNEW, kids were NOT for me.

WHY??:
I do not have patience
I am not comfortable around children of any age
I am not willing to change my life THAT much for another person
The commitment is too great
Children brought up by parents that are less than devoted turn out as LOUSY human beings, so why would I want that??

I think you get the idea.
