You figure avoiding stranger danger is more important than being polite. You backtrack through the library, back to the roof, and just as you’re about to climb down to your bike, you hit a rock and trip, and all of a sudden you’re falling… falling… thunk.
You look up as your vision fades. You’re in a public place, so maybe someone will find you soon. Your last thoughts as you slip into unconsciousness is that maybe being polite is the answer.
THE END. Try again.
