I used to live opposite a classical instrument repairer called Archie McPhearson, who would sit and talk to you for hours if he had the chance. It could be a bit concerting as he had one wonky eye that would not point at you when talking.

He was one hell of a craftsperson. He occasionaly repaired electric guitars and basses. I once brought him a guitar where the neck had been sheeared completely off. He completely shocked me by providing a repair that was close to invisible to the eye.
