I was looking for something to do and I noticed that I would run past many sleeping Glitches. I had a surfeit (I love that word) of paper and thought, "I wonder if I could leave them a note that they wouldn't find until after they wake up and I'm gone." It turns out that so long as they had room in their inventory, I could. So I wrote them a note and told them that if they mailed me the note I would give them a small gift. Lo and behold a while later when I passed a mailbox I had mail waiting for me. I sent them back a note with a gift and thanked them for returning it. A few days later I got a note from someone who I had not given it to. I turns out that the person I gave it to left it on the ground and someone else picked it up and returned it. Now I have lots of friends and most mailboxes tremble when I walk past.
