Apologies...
if you have received a Learn How To Park Moron card on your vehicle and you...
 

A. ...just learned how to drive/park yesterday.
B. ...are physically or mentally handicapped.
C. ...are elderly, or a disabled war veteran.
D. ...are visiting or have recently relocated from a third world village where transportation involves only bicycles, donkeys, or camels.
E. ...are legally blind.

Did somebody leave a LearnHowToParkMORON.com card on your car?

It's probably because you made it difficult or impossible for someone to park or get back into their parked car by either parking crooked, too close to one side of a space; or wasting curb space by leaving too much space at the end of the curb.

This is
RUDE
SELFISH
ANNOYING
THOUGHTLESS
INCONSIDERATE
and downright
OBNOXIOUS!!!!!!!!!!!!!
