My folks were both born in Latvia, and there's no noble blood I'm aware of. So, yeah, it is pagan peasants all the way down. I used to go to the St John's Day celebrations with my folks, and while I was too young, there was definitely bonfire-jumping going on.

Mind you, my resistance to sleeping in is clearly more personal habit than breeding. I only developed an early clock when I started needing to be in an office at a particular hour. And napping - I'm all for it!
