This shot is quite obviously different from the other shots I have looked at so far as it is focusing on two people. The different expressions each of their faces show us how comfortable they are in social situations like a cafeteria. The two main characters are the only two actors that are in focus as the rest are out of focus behind them. They are almost completely still yet everything is moving around them. This emphasises how they stand out compared to the others there and that it is almost as if they just should be there (which is how the main character feel during this scene in the movie).
