What's the Point?

What's the point of the story Document? To me, there is a lesson to be learned here. I still stand by my assumption that the girl in the story is trying to communicate something to the protagonist; namely that she is leaving, or is about to leave or give up on him, or something of the sort. This is evident from what the story 'Disappear' is about. A woman who is slowly fading. Like she is disappearing from life itself. Next, if both of them are comfortable enough to go in and out of the guys room, so much so that the landlord assumes her to be his girlfriend, then to me these are signs of a certain comfort between the two. This doesn't necessarily mean there is a romantic or physically intimate bond, but there must be something happening. The main character doesn't seem to understand this, because he strikes me as socially inept and awkward. So what is the lesson to be learned here? It is to act, before it is too late, because if you procrastinate, you may just end up regretting it and losing something that is dear to you. Now, the main character may not be aware of the fact that the girl likes him, but the story does spur his thoughts and gets his gears turning so to speak. A whole spectrum of possibility has been opened to him through the story. He didn't recognize the opportunity of being with the girl for what it was, thus putting him in this precarious position now. So, the greater point of the story is: Seize the opportunity.
