Class never makes excuses. It takes its lumps and learns from mistakes. Class knows good manners are nothing more than a series of petty sacrifices. Class bespeaks an aristocracy that has nothing to do with 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. The person with class makes everyone feel comfortable because they are comfortable with themselves. If you have class, you have it made. If you don't have class, no matter what else you have, it doesn't make any difference.
