"A profound unmitigated loneliness is the only truth of life"
- R.K. Narayan

Some movies are made purely to entertain, some to make money, some with a focus on selfish career motives, while some are a burst of creativity. PK could have easily fallen into one of those brackets had it not simmered with an undertone of innocence that struggled with the hunger pangs of an unfinished journey. There are many defining moments in this movie, and all of those fall in the categories mentioned above, save for one -  the moment when innocence asks wisdom, "can you take me home?" This moment is the real reckoning for a filmmaker who is probably more than what he knows about himself.
It was a desolate afternoon. She sat on a pedestal under the tree, and I stood in the sun across the street. She didn't seem to notice me, as she opened the hooks of her blouse. I couldn't help but notice her... doing it. She was preoccupied with the sack resting on her lap; while I was burning, not just due to the hot sun above, but from something within.
