“We could change the world, the two of us,” Sam says, in that voice that’s too sincere to possibly be real, except it’s Sam, so it is, and the naivety of it is almost as endearing as it is breathtaking. “Really make a difference, you know?”

You could, Josh wants to say; Josh, who doesn’t have the ambition to change the world, just to make his part of it a little bit better, a little bit easier; Josh, who sees Sam’s future in his perfect face clear as day: well-connected career, a wife as accomplished as she is beautiful, two kids, a dog, the whole picket-fence all-American sweater ad life that he’s got ahead of him - and Josh, well, maybe he’ll be the guy behind him, if he’s lucky, so all he actually says is, “Yeah,” and pretends Sam’s smile doesn’t cut down to the bone.
