They don’t tell you how lonely it can be, living in a world like this.
When you and your family, or friends, used to play around about who would survive an apocalypse the thought never occurred to you that you would be on your own. You surely didn’t think you would be the one to survive, and how much you would hate it.
It was pure luck that caused you to find the waterfall. You never had much luck in the past life but this life seems to be teeming with it, overwhelming so. It’s a miracle you found this sanctuary, and that no one else has claimed it before you. You would look for others but it’s not safe. Despite all the luck you have, the only kind you seem to run into are the crazies; they either want to eat, rape, or enslave you. So you’ve become accustomed to being on your own, something that is completely new to you.
Anyway, the waterfall keeps you company. If you try and listen well enough you can create a song out of the sounds it makes. Besides hydrating you, and feeding you once in a while, it keeps you from going crazy. The constant flow of water becomes a natural hum after a while, which can lull you to sleep. Yes, you’re alone but at least there’s sound. And for now, that’ll have to do.
