Happydays, I'm not offended in the least and please don't appologize. That you wanted! your children and love spending time with them is only a good thing, albeit that it is simply not a desire I share.
While I feel slightly jealous that you've had the sort of experience which I needed to have, this jealousy isn't personal or destructive, just a generalized feeling, and in many senses it's probably good for those who haven't had to make a resolution like mine to think that such things are! possible for a surviver.
So, please don't feel sorry.
