I'm trying to create this new story, and I've figured out that the skeleton of the plot for the most part. But part of the plot I'm struggling for it to make sense. Basically it works like this: Person A and Person B grew up together and were close friends. At some point (it can be at any age), there is some "event" that ends up with the two of them spending the next 5 or so years in completely different cities, not talking with each other or having any communication with each other during that time... Person B is completely bitter towards Person A about the "event" yet Person A has no guilt about said event and doesn't even suspect Person B would be bitter. The only idea I can think of right now is that the two of them had a fight of some kind, and due to some kind of miscommunication Person A thinks that Person B no longer wants to be friends and outside circumstances (new job, college) force him to move away without being able to speak with him again. And perhaps Person A left a voice message or a note trying to explain but it never got to Person B and that only compounds the bitterness of finding out the guy just took off. I don't know if this even makes sense or sounds too complicated to work or what.
