My wife and I like to leave behind clues that we're a couple on the run when leaving budget hotels. Empty hair dye boxes, cut-outs of passport photos, randomly annotated maps. Never get to see e fruits of our work, but I hope it has the desired effect.
@fesshole That sounds like a lot of effort.
I just open the ubiquitous Gideon bible, cross out "In the beginning", and write "Once upon a time".
