Its a little more PC which may be frowned upon, but............. write a quick note saying:
To the owner of xxxx im sorry for Kicking/punching/elbodropping/keying/pissing/all of the above on your car but your inconsiderate parking enraged me. After seeing the damage I caused to your HOS if felt bad so i wrote you this note so that you learn and park more consideratly next time.
They'll be stoming round their car for a while looking for damage!
