My fear about having kids... what if I hate them?
Some people have kids they adore. Their kids are their life.
But what if you have kids who just don't gel with you? If you were a kid, they'd be the kid you hate in your class. Maybe they're a bully. Or twisted.
Except you're not a kid, you're an adult and you're stuck with them.
I'm sure there are many parents who have kids they struggle to like. Or parents who are jealous of other people who have likeable children.
I think historically, parents would send their kids to boarding schools if they didn't like them. Or to their grandparents farm.
