I like the idea behind this - words and silence, and their significance to both these characters. Haven't seen the movie, but it's still pretty obvious what the concepts mean to them -- or at least, it looks like to me.

I think it's cute that the kid with the stammer is the one to win the argument against the other who's clearly pretty good at debate, and (I guess) used to winning them, too. Cuter even that maybe for once he doesn't have to win this one, and he should just...say nothing. (well, maybe he should kiss him again, instead - that'd be nice. *giggles*)
