Two weeks ago I had many suction cup type things attached to me at the sleep clinic, which all came off early the next morning. Some of them left red marks for the rest of the day. One of them was really special though. It left a red mark that has lasted two weeks so far. See?
I think it's permanent! I also think that picture is weird and it's kind of hard to tell exactly which part of my body that is. Maybe this should be a contest, in which Sherpa gives a prize to the person who guesses correctly.
