Sadly it is unlikely to be me, it is a while since I have given it a go (although I will today, thanks to you, so you are instead paying it on lol)

I heard your "I made this" in the voice It really made me feel like I was sitting down to something lol.

How you present it, as almost a conversational anecdote actually works with the tailed off ending. It makes the scifi concept this is built around seem a lot more believable, someone just casually remarking in passing about the effects on the places he delivers them to. I am intrigued as to what he was going to say though. Was he going to confess to his own bot, reference something entirely alien (given the humans reference), or could he have been conspiring/arguing against the bots existence, or reveal something totally different. I love a good open ending, and you manage to fit enough elements into this to allow for a whole range of entertaining speculation!
