Audience of none

What is he doing? What is he thinking? What is he saying?

I honestly cannot hear the guy. A large plate of glass and about a hundred feet separate me, inside doing homework, and this man, outside in the park blocks of PSU. He stands there 90 degrees opposite me, standing and singing. I assume he is singing because he has a guitar and it looks like he is singing. That is not what is abnormal. Those facts don't make me stop and think. I have seen people sing in a park before. The part that does is the fact that he stands there alone, for one, and also no one cares. At all. The people within ten feet of him seem completely unaffected. The people walking by don't seem to care or even acknowledge. Nobody looks up. Nobody looks away. Passerby's and pedestrians are absolutely indifferent to this guy. He just stands there, alone, singing.

But I continue to wonder, why is he there? Why does he continue? Could it be his courage that he stands in the open square unaffected by what people might think or do? Or could it be a total attitude or narcissism that propels him to self-promotion. I still cannot hear him, so I cannot form my opinion on how good or bad he is. He is just this guy, with a guitar, in the middle of a park.
