Great little mystery. You did a nice job setting the scene and showing the how the narrator’s concerns developed.
Need a sequel my friend, I’ve seen a lot of different interpretations of how teleportation could work. How it should work. Look up a story called “The Jaunt” by Stephen King, it’s interesting, to say the least
Thanks, guys. I’ve actually read The Jaunt and that kid’s last line haunts me to this day. King’s best work is his short stuff, I say.
