Alright, so I just finished chapter 3! I really liked it, and not just because I really dig the obviously implied pairing. I just all around found it entertaining; and by the way, you're an extremely good writer. Very structured, but flowing as well.
I did, however, want to bring up a few things. For starters, it was the way Paulo reacted to the barking. Not his running out of the auditorium, but rather, his thought process. I think running out of a dance crying because of some irrational fear would be rather traumatizing, especially for a boy like Paulo. I imagine his mind would be in far greater disarray. Generally speaking, he appeared to be pretty calm about the whole thing, albeit slightly angry. I think in light of a situation like that, he would be thinking irrationally and he would be questioning himself. He would also be questioning his questioning. And he would be questioning his doubts. Really, he would just be thinking faster than he could reason, thus resulting in the cause of that typical description of a "storm in one's mind.
Second:
Quote
Come on, Paulo, is that's what's bothering you?
I believe you mean "is that what's..."
Third:
He refers to himself as aloof. Does he really know what aloof means? Now, don't get me wrong, his usage of this word might actually be very clever. Maybe he picked up what it meant from English. Maybe you're trying to portray him as more intelligent than he is normally seen. And maybe he really doesn't know what it means at all, but I just figured I bring it up, because honestly, he doesn't strike me as a guy who reads much -- it is actually implied in this story.
Other than those minor things, I'm enjoying it, and I'm really looking forward to seeing more by you.
