Road etiquette

Warning to all useless drivers: If you continue to ineptly park in front of my house, taking up two spots with your willful inconsideration, I will write a polite rebuke and place it under your windscreen wiper blade, where I hope it will initially look like a parking ticket and thereby give you a double-shock.

Learn to park, people!!!

(Could I get away with a small traffic-crusader cape to wear at such times?)
