If you have any normals and you're up at 6 and they're in their homes, chances are they'll be asleep. They appreciate you waking them up. "It would have been silly for me to go back to sleep after getting up early!" The expression of surprise on Skye's face when you wake her up is adorable.
I've only got one stump in town, and I've seen Harry and Mallary sleeping on it. Harry sleeps on the bench next to his house. You can also catch them sleeping in their houses about an hour before their bedtimes. And, it's not just normals who fall back asleep on their feet during their waking hour.
