I've been told to do a particular favor a peculiar one, like a post-it stuck underneath the surface of the desk do a favor and run a hand down the underside ignore the gallant arrangement of hardened bubble gum there is a post-it with a lost message so I have been told I took the post-it and found a single word written "Hello" in pencil in the most awful handwriting and I took a pen and wrote a greeting below sticking the post-it back where I found it. And the next day I found the pencil erased so all that was left was my own "Hello." and I could never figure out quite why that was so
