Instead of being shocked, dismayed or upset RJ is angry and indignant. How dare the Reaper make a mistake and interrupt her busy teenage schedule.
She insists on being sent back pronto.
Essentially this story is about having the chance to rectify mistakes, to take the right path instead of the wrong one and being given a second chance.
Each interaction we have with another human being moves a cog in life. Depending on which direction it moves it sets different things in motion. So it goes without saying that changing one movement or direction in one cog can change a life.
The powers that be, and there are quite a few in the Heaven/Hell/In-between station, finally decide RJ at least deserves a try at being a better person. So she gets placed back into certain situations in the hope that she will make better choices for herself and for her fellow human beings.
Schmitt lays at lot of emphasis on bullying, peer pressure and taking responsibility for your actions. The underlying message being; how each of us and our decisions can impact others.
If our interactions with others are negative then perhaps we are leaving a trail of destruction behind us. Instead of ignoring the bullied kid in the corner maybe you should talk to them. If being with the popular kids means you have to be mean to others then maybe you need to find new friends. Do you ignore it when others are being picked on? Stand up and speak out.
A strong message to young people, but wrapped within a story, which is both witty and serious at the same time.
