Do you see that man over there? Yes him. Sitting on the bench. The unkempt character. The one with the unwashed clothes. Badly in need of a shave and a haircut. Him. Him. Drinking out of that beer can. Yes that's the one!
Well don't worry. He will not do you any harm. In fact if you ever need a friendly ear, he is the one to go to. He might not look it on first appearances, but underneath that rough exterior their stands a thoroughly decent man.
Now take a look at that man over there. Yes him. The smartly dressed one with the nice suit, and the leather briefcase. Can you see how shiny his shoes are? He is talking to that posh looking woman with the blue hat. Just shaking her hand now. Smiling. Just waved goodbye to her. Yes that's him. Pillar of society he is. Does a lot for charity. Church elder.
Do not trust him. He is an evil bastard. He likes to hurt children.
