Take a story's temperature by studying its tone. Is it hopeful? Cynical? Snarky? Playful?
Self-centered, Exasperated
Alexander tells the story through his own voice, which is cynical, dramatic, and just plain fed up with everything that's happening. Of course, his view is entirely self-centered: he doesn't consider in any way how other people may perceive the experiences he has or the interactions he's involved with; and any input from others is either paraphrased ("My dad said please don't pick him up anymore" [20]) or simply generalized and described ("No one even answered" [4]).
But that's just Alexander's point of view, so of course it's self-centered. We are all the stars of our own movies, right?
