... in the middle of the night.
in his sleep.
Yeah. You know how the sides of the beds are up against the edge of the canvas tent part?
I guess we hadn't tightened them enough, and one morning when we got up he wasn't there.
We found him sleeping on the hard ground having slipped between the bed and the canvas side.
He fell the 4 feet without waking up enough to come back inside.
That's never happened to me.
I think that's why I still have hair but he doesn't.
