I wonder if part of the magic is being hand-written. Would it not work as well if it was typed? Does it matter what color ink or what type of paper you use? Or am I totally on the wrong track, and this person just prefers writing over typing?

Either way, I find it incredibly tragic. Seems like their car was involuntarily towed, which is already a bad situation, and this is going to make things worse. At best, it will cause delays.
