You come into work one morning and the dry erase board on your desk has a note on it that you didn't write. You assume it's a coworker friend so, just to amuse yourself, you respond to the note on the board with your own note. The next morning you come in and there's another response, only this time, the response isn't so friendly. What happens next?
