What did the film have to do with writing?

This film was amazing, sad, and a great story. It was about every emotion mixed into a video. This film could have many things to do with writing. How for the guy himself, it came to his only way to communicate, which was writing. How it has to do with me writing personally, I can't see much, other then it would give me an amazing story to tell others through writing. But another thing, the person who was talking through the main characters point of view, he was reading from what the guy had wrote through his high tech device. It shows that even when you can't talk, you can still write. You can write to tell your story, to vent emotions, anger, jealousy, love, all on one peice of paper. This film shows how writing could be used as a tool. As I said previously, a tool to get your story out there or to express how you feel if you can't put it in words.
