The phone just rang, but it seems no one's home. Like, literally. It's as if the residents of this planet just decided to up and leave without a word. No forwarding address, no nothing.
Try checking the fridge, maybe they left a note.
Or perhaps they're just really good at hiding. Like, ninja-level good.
They just pretended they were never there It was just a very long holiday Possibly they're just very good at napping
