Not being a whiz on cars, I feel inadequate when talking with a mechanic. When my vehicle started making a strange noise, I sought help from a friend. He drove the car around the block, listened carefully, then told me how to explain the difficulty when I took it in for repair.
At the shop I proudly recited, “The timing is off, and there are premature detonations, which may damage the valves.”
As I smugly glanced over the mechanic’s shoulder, I saw him write on his clipboard, “The man says it makes a funny noise.”
