I agree completely – about the only non interesting conversations I’ve overheard in a restroom were at work, and that’s because you never know if a manager is in one of the stalls! :)
I’ve been known to read a book AND have a beer. I’m not sure why you labeled it “mature” because it doesn’t strike me there is anything objectional in it. Your dialogue is very truthful.
Well, part of the mature rating was because there’s reference to sex, and part is because the sequel portion is also mature and as one segues to the other… I just thought I’d cover my bases, just in case.
