All the singletons at school were different to the rest of us. They all seemed happier in the company of adults than with other children, and they didn't or couldn't fantasise about stuff like other kids either, almost as if they couldn't play with other children. One aged nun I spoke to whilst crossing to Ireland said "I always think a single child is a lonely child". The same nun also said "if you are born a dunce you will die a dunce". When as an adult you tell a child off for doing something wrong, one can sometimes make a mistake and get it wrong, in such cases the other child will speak up for it's brother or sister but a singleton loses out on that advantage. My ex-wife would have stopped after one child, but the then nanny said 'when we were long gone they have no one of their own around', so we had two. They are good friends and the eldest who has a more hesitant outlook on life, gains confidence from her younger sibling who doesn't seem to have a nerve in her body. Had I been rich I would have liked a larger family, but I don't think that would have happened with that spouse.
