How is the theme of connection explored

In contrast to the theme of loneliness and isolation, we watch as Theodore finds connection with the world around him, encouraged by his connection to Samantha. By opening up to his nonjudgmental computer, he is able to look out at the world and realize the ways he is meant to be a part of it. Connection with others is modeled by Theodore's connection with Samantha, and as they spend more and more time together, Theodore feels encouraged to connect with others in his life. It's because of this interpersonal connection that Theodore is able to take his eyes off the past and begin to see the world in front of him, going out to drinks with Amy, going on a double date with Paul and Tatiana, and generally marveling at the people he encounters in public. Ultimately, even though Samantha leaves, Theodore is able to take the feelings of connection that their relationship modeled, and use it to grow and evolve into a more emotionally open person. After Samantha leaves, rather than recede into obscurity again, he writes an empathic email to Catherine, and goes to visit his friend Amy for comfort.
