And yet...

I like this analogy - sparring with each other like toddlers do, before realizing that they have a lot in common as they age, like the English language, industrialization, the systemic abuse of natives, Big Oil, the World Wars and racism.

Now that they're older, they're sparring once again, just like siblings do over the parents' estate.
