Neither genius, fame, nor love show the greatness of the soul. Only kindness can do that. It knows that a good laugh is the best lubricant for oiling the machinery of human relations. Class never makes excuses. It takes its lumps and learns from past mistakes.
Class bespeaks an aristocracy unrelated to ancestors or money.
Some extremely wealthy people have no class at all, while others who are struggling to make ends meet are loaded with it. Class is real. You can't fake it. Class never tries to build itself up by tearing others down. Class is already up and need not attempt to look better by making others look worse.
