This week's theme from Wandering Through the Shelves is about Narrators that never grace us with their physical presence on screen. I ended up having to cheat a bit with my 3rd pick.
1) Little Children
An unknown man narrates this story about two people, their infidelities as they meet up on play dates with their children, and the recently released pedophile in their town.
2) (500) Days of Summer
Another unknown man explains Tom's mindset as he thinks he's found the perfect girlfriend in Summer.
3) A Christmas Story
This is narrated by adult Ralphie, who technically never appears on screen. I tried to avoid using this one, I really did. But sometimes you just have to go with the first film that comes to mind.
