People who don’t know Harry tend to underestimate him. They cast a skeptical eye on his typical outfit: ragged jeans and shirts that bear evidence of his most recent meal. And his most frequently uttered expression, “Waaaal, I just don’t know,” can make him sound less than bright. So, some enter a negotiating session with Harry relaxed and confident that their side will prevail and that Harry will gain no concessions for his group. That assumption is one that Harry cultivates, and it is a big, big mistake.
