Hackman or 'Hack' to his friends, family and shrink, is very set in his ways. Rarely stuck for an answer, he feels he has a Sgt Bilko rapier-like wit, but deep down, he's as insecure as the rest of us. He worries about being laughed at and assumes he's part of a 'con' before it happens. This gives him a very blinkered view of life.
