How we cite our quotes: (Chapter.Paragraph)
Quote #1
"Do you notice things like that, Marcelo? You know, when a woman is hot to look at, pleasant to the eyes, attractive? Do you get that urge we all get when we see a good female body?" (7.66)
Marcelo doesn't even know what the urge is yet, which makes Wendell's question one of the most confusing ones he's been asked in his short time in the real world.
Quote #2
I know that Wendell's finger poking is a gesture meant to signify sexual intercourse and that the rising arm signifies an erection. The rules regarding sexuality and conversations about sexuality are hazy, confusing. (7.87)
What Marcelo doesn't get here is that there aren't really any definite rules (other than not hurting anyone, of course). Wendell's being crude and obnoxious, but he's not breaking the law. He's just making himself look like a jerk.
