Sure, that'd keep rhythm and steps going, but it wasn't the same thing that he loved, and it was so solitary, and Jeremiah simply wasn't a solitary person. It was why he was out here in the first place, because after several weeks of being mostly holed up in his house, he had gotten tired of only hearing himself talk to himself, and then feeling like a crazy person because of it.
