The mechanic across the street takes some educated guesses when he repairs cars. He looks under the car hood and thinks about cars that he has fixed. He may even remember the workplace vehicles. He fixed them too. He works so quickly that he may not know why his hands move in the direction that they do. He may reach for tools to do his repairs faster than he can tell you why. Somewhere he knows even if he can’t or won’t say.
