Sound Unit: Ideas

For the sound unit I have thought of some ideas and how they could work, my first idea was to have an "unfortunate" journey which is a story of a student who wakes up late for uni, and things go down hill from there,e.g. he runs out of hot water in his shower, he almost gets hit by a car, steps in dog poo etc. and when he arrives at uni he finds it's closed and the journey was a waste, this is my initial idea but I feel that there needs to be a twist e.g. he finds a love interest or things start to pick up. I feel that I need to pick apart this idea and find it's key points to get the most out of the story.
