You don’t have to act interested in my child. It’s cool. I’m not that interested in yours.
There are some children I quite like. Usually any child I’m related to. I think it must be some throw-back caveman instinct where I’d be expected to take over for my sister if she got herself mauled by a saber-toothed tiger. Likewise, I’m quite fond of the babies of my mothers group. I guess some part of me recognizes they are my “village” and therefore their children are also my responsibility.
All other children?
