Story idea about the dead dude

So, apparently, I had it flipped when I was telling you guys. The dead guy is the hero of the story. The ideas for it came flooding back when I read this little note.

Preston Lewis  -Dead Guy, generally unimportant to most people, just a blur in a crowd of people, maybe depressed

Randall Hughes – Loner, finds Preston, thought he was a better friend than Preston actually thought

Preston is a 43 year old man, not in the best health but a generic man, ethnicity is unimportant. Worked in an office, 9-5 for twenty years, life is generally bleak. Had many big dreams but no drive or ability, maybe lacked the courage. Never married, no kids, no crazy stories to tell. A very good listener. Dies in his car at the office parking lot, listening to a travelling podcast about finding the courage to chase his dreams on repeat, likely burnt to a CD as he was an old fashioned man, didn’t like technology that much. His car was nothing fancy, white but needed a wash, cracking leather seats, one window broken and taped up, fast food wrappers on the ground. 

Randall is 24, low man on totem pole. Beta male, easily. Identifies with Preston and sees him as a success due to low expectations, mostly, or poor role models growing up. Skinny, quiet, an easy target for overly confident folks or those that are mean spirited.  He is clinically depressed, has a history of outlandish behaviors as a teenager, actually a highschool drop out due to behavioral reasoning. He has since mellowed but can be impulsive. Has no pets, watches lots of movies, no family he is willing to claim, no real friends except for Preston. When around Preston, he tries to make his friend laugh, enjoys hearing his dreams, has him on a pedestal that is almost unhealthy but he tries very hard not to cross any lines.
