Thanks for chiming in! I wish to have what you two have in knowing and sticking with not wanting any. You're right about the point of regret. I don't believe that I will, regardless of how my mom feels about that.
It sounds like your mum has a lot of them already. Grandchildren and wow even a great grandchild! You're so right about the reasons, and I believe the socialization one for sure.
In the case of your wife, she is the final one but I'm curious if you ever had someone you liked and was with for a bit who might have wanted them, even though you didn't?
