For reasons personal and interesting only to myself, I’ve been thinking about people who complain regularly (often with the preamble that they aren’t the type of person who likes to complain), and the very old expression about which wheel gets greased. There is truth to the phrase, of course (otherwise, it likely wouldn’t have survived as long as it has) but it’s only half-true. I prefer my own version of that expression: “The squeaky wheel gets the grease, but the wheel that squeaks and squeaks and squeaks gets the grease—then gets its whiny butt replaced at the earliest opportunity.”
Unfortunately it’s a bit longer than the original, and for that reason will probably not catch on.
