"... I wonder, in being childless not by choice, how much of the pain comes from the lack of children in itself and how much from the society?"
I think it is an excellent question.
I replied that I would define my pain with a formula: 30 % lack of children, 70 % society.
I had some days to think about it and the formula it is true for me now.
But in the very early day of infertility, it would be like 90 % lack of children, 10 % society.
Enough of thinking. It is now time for one hour of swimming in the Olympic pool with my mum.
(I definitely inherited my love to swim from her)
