Modern Interpretation: There's always that one dude who has whatever the hot sneaker of the moment is, no matter how hard they are to get. Don't mess up his day (and yours) by immediately hitting him up for his source. Number one, he's probably been asked a zillion times already. Number two, the way you KEEP a good connect is by not telling everyone about it. Number three, if you play it right and don't get all crazy stalkerish, maybe he'll tell you eventually on his own. As with the previous commandments, patience is a virtue.
