Ah, that wonderful, heady, self-satisfied feeling you get when you're perfectly sure that you know everything! You don't mean to sound arrogant -- you're just explaining the concept to the poor simpletons who surround you. Here's a heads-up: Back off a little.
You could be embarrassed by someone even better informed than you, who humiliates you in front of your adoring crowd with facts and figures that shoot a big hole in the Hindenburg of your mind. Or, you could get so excited or so nervous that you trip over your words, eliminating important points or massaging facts into propaganda. So, remembering that pride comes before a fall, eat a healthy helping of humble pie and keep your contributions to a minimum now. Listen up; you could learn something quite useful. This is a good time to practice on your writing skills, or further develop ideas you've been working on. Strive for complete honesty in communication while making a point to truly listen to what others have to say.
