I'm kinda emotionally drained at the moment (but I got my 500 words done!) so today I give you a random writing prompt.
Pick a confidence trick from this wonderful list (and you should read these anyway, can't be too careful!), and then write a short story or brainstorm a story idea wherein someone uses the con with unexpected results. And if that's not enough of a prompt for you, throw in a toaster.
Happy Solstice Everybody!
