A lift is the location, self-preservation is the theme. A television is an object that plays a part in the story. One of the characters is trusting and impulsive but can be outspoken and is scared of bees, another is humble and self-assured but can be loud and is scared of failure.
Most of what I write is science fiction and fantasy, but this one came out in brainstorming as contemporary fiction featuring a serial killer . . . because I watch too much Forensic Files. I sort of finished the outline of the story . . . although some of what happens will depend on some research I need to do.
