"Dad always warned that it was misleading when one imagined people, when one sas them in the Mind's Eye, because one never remembered them as they really were, with as many inconsistencies as there were hairs on a human head (100,000 to 200,000). Instead, the mind used a lazy shorthand, smoothed the person over into their most dominating characteristic--their pessimism or insecurity (something really being lazy, turning them into either Nice or Mean)--and one made the mistake of judging them from this basis alone and risked, on a subsequent encounter, being dangerously surprised."
