Postman's Etiquette

I wrote this script for a "competition" where there were 3 rules: Have a postman as the lead character, the theme is etiquette and finally it must be max 10 pages. Well, 2 out of 3 ain't bad! I just had to make the story longer than 10 pages because there are multiple storylines here that interact. Also, I really liked the time travel concept but I needed the protagonist to have a longer story so that I could show off the time travel concept many times over in different settings. And I needed him to explore the time travel and use it in new ways while he was growing as a person. The plot may be a bit complicated as time travel movies tend to be but I kept the dialogue very simple and direct. Edit: I have been trying to make the time travel concept easier to understand. But I still need to rewrite it a few times before it's a good script. Right now it's just okay.
