I had a friend from psu who flunked out when we were juniors. He sort of drifted off to Florida, and eventually ended up living on the street. Before long he joined the military. (I'm keeping it brief as I can.)
25 years later, having worked through the ranks, got his degree and become an officer, he is up for the promotion to the grade in which he will probably end his career. But he needs a security clearance. Enlisted men government investigators ask him if he's ever smoked dope. He's been counseled by his buddies to be truthful, because lying is worse than smoking dope or other misdemeanor shit, right?
So after he says,"Yes," the guy says "How many times would you say, sir?"
He thinks for a second and says, "about 2,000."
Long uncomfortable silence. Then the guy says, "Sir, that is going to be a problem. Tell you what. I'll put you down for 2."
Got the promotion! Hope this helps.
