What you saw is so sick a joke you feel a sense of remorse for the poor fool. You stand up, and ponder, wondering if he does realize the situation and what this might do to his own future. It strikes you that if what was told of the Park and its strange amusement of making some people feel, look, and becomes as donkey asses; then of what you see happening here is terrible and troublesome.
"Why," you ask, are you not a bit concerned!" Pointing at the animalistic appendage protruding from out those tight pants, it sways and whips violently, as its owner continues to display more attributes of becoming more than just asinine.
A goofy big buck-toothed grin is all you get as a response.
The wide eyed, dumb looking grin begin to relate in your mind that this young fool is one of those chosen few, he likely will finish his day at the Park by standing in some barn stall. It is obvious what the fellow feels of his drastic changes comes as if a joke, elating him into a sick and ultimate, permanently degradation of his actual self.
The is feeling a change of heart toward all around him. As if his thinking is changing, considering those who were friends as if they are in fact his competition, or competitors in the living of life.
Stunned a little to his holding up his hand and showing you a middle finger toward your face, an indignant sign he would not have ever used toward you if he did not feel as bestial as the way he stands as an example of youthful brazen ignorance.
