All my life I have enjoyed taking things apart to see how they work. I have not always been successful at restoring them to their original configuration, but I could at least get them to function again (most of the time). Besides, as any good shade-tree mechanic knows, there are plenty of extra and unnecessary parts that do not make their way into reassembly. We just cannot always tell you what those parts were intended to do or why they didn’t find their way back!
