Class never makes excuses. It takes its lumps and learns from past mistakes. Class knows that good manners are nothing more than a series of small sacrifices and minor inconveniences. 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 is comfortable in its own skin. It never puts on airs. 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.
