Drifting in the World My Text-Book sort of comments:
It is a good record of a normal night life in the 'cultural capital' of the contemporary confused society of Pakistan. Where the narrator is trying to address the intellectual demands standardized by the developed countries while at the same time showing his preference for the local flavors over the 'others'. Followed by a good commentary on the collective indifference of this society towards its surroundings but on the other hand their futile but 'juicy gossip' about the global and local politics.
Amjad and Mehboob present the dichotomy that most of the Pakistanis are trapped in. Amjad, while doing a 'sinful' act is asking for forgiveness, while Mehboob clearly making fun of the 'holy war' and its promised fruits in the hereafter. Pakistanis are stuck in the land which was declared a Secular-Islamic state and we still don't know actually who made this country? We haven't yet decided that any exploitation/offense is a sin or a crime.
This story is a beautiful depiction of this confusion.
The answer to Nikhat's rhetorical question: If just by being part of life can justify these, then everything is justified, as everything is part of life.
