That line is usually followed by a simple idea like this:
To see someone’s true character, observe just these 2 things:
- How they treat people who can do nothing for them (like waiters, cleaners, strangers).
- How they behave when no one is watching or when there’s nothing to gain.
Different versions exist, but the core message is the same: character shows up in small, low-pressure moments—not in public performance or when there’s an audience.
