In my opinion, I think different aspects of the human nature are very well reflected in this very interesting short story. Despite a few shortcomings, there are lots, each deserving of a due attention. The asserted fact that the young waiter did not wish to be unjust. He was only in a hurry is quite thought-provoking. Well, he has been unjust in my view, was it his being in a hurry? I am still wondering because I am living in a big city and am in a hurry most of the time! The other waiter tries to comfort himself and says it's probably insomnia. Many must have it. Does he simply feel lonely or it is that nada thing or the nada thing is loneliness?
