You are a failure.
You haven’t ever done a single thing of worth.
You have decided to die.
…but, of course, a failure like you couldn’t even achieve that.
At least, not until you saw the notice looking for test subjects for an experiment. One that promised to easily, painlessly, allow you to end your life while saving someone else’s. So you decided to apply and…against all odds…
You actually managed to luck out.
Now all you have to do is not fuck it up.
