This is the second audience member we meet. He also has the distinction of being just about the only consistently happy dude in the poem. Seems like he's had a great year, even if everyone else was crying and getting old and trembling in fear. The "Optimist" is the speaker's name for him, and again, that's pretty different from calling him "Victor" or "Rob" or something like that. In a way, he feels like a stand-in for all the happy, lucky people in the world.
