Survival Has a Memory
Those ungrateful ingrates would go mad, but how was that my problem?
I had once survived on an abandoned island for two months. My phone was turned off. I'd power it up and call someone if I really needed help.
Thanks to my frequent survival trips, I knew the local rescue squads well. All I had to do was send a signal, and they would send a ship right away. Then, help would come in two days' time.
…
I toiled away for the whole day, and night was soon upon me. I sat on the little bench I made, staring at the blazing setting sun as I munched on the seafood I had caught with my traps.
