I can completely relate to the scene where he is waking his parents up in the middle of the night to search for his wedding video in their room at 3 AM where he is tearing through their stuff looking for it and accusing his mom of hiding it. It was really common for me to get fixated on a really random missing item in the middle of the night, and I'd start accusing people in my house of misplacing it and search for it for hours in hysterics, even if it's just a $5 unimportant item that I haven't used in years (but in my head, I'm going to use this item for a "very important purpose").
I can also relate to when he is expressing his feelings about the Ernest Hemmingway book.....
My poor mom for all the times I stormed into her room!
