I generally say things like “it’s complicated, but let’s see if we can find out.”. Unfortunately when my daughter said “Why are your parents divorced,” I had to leave it at “It’s complicated.” Basically, magnets.

That reminds me of the myth related to the daddy long-legs, that it has the most potent venom of any spider but can’t break your skin.
