Hannibal’s flirtations are so intimate it drives me crazy. “You just came here to look at me.” “When life becomes maddeningly polite, think about me.” He makes himself the subject–Will should look at him, think about him. I’m at the heart of your issue; indulge in me. The second line is especially sensual–the contrast between the aggressive ‘maddeningly’ with the soft 'polite’; when life drives you crazy with its impersonality, you’ll find your relief in me; in your thoughts about me.
