What is the most awkward conversation you had with your child?

It wasn't with my kid but rather with one of my friends' kids here in Sweden. The little sweetheart asked me why I looked different from my partner (he's blue eyed, blonde hair) because her mommy and daddy look the same. It was awkward trying to explain race, harder than it sounds. I eventually showed her a youtube video of Disney's Pocahontas (which she loves) and told her that me and my fiance are just like Pocahontas and John Smith. Hahaha.
