It might just be the rudest note EVER!
A Reddit user has shared a letter they found wedged under the windscreen wipers of their parked car.
'PLEASE DON'T BE A SPACE HOG,' the note begins, rather tamely.
'SHOW SOME COURTESY TO EVERYONE ELSE TRYING TO PARK ON THIS STREET TOO!'
But the writer quickly begins hurling insults.
'GET THE F' OUT OF YOUR CAR AND LOOK TO SEE HOW MUCH SPACE YOU'RE TAKING UP.
'IF IT IS AS WIDE AS YOUR A', IT IS TOO MUCH. Get back in your dinky little car and fix up your p***-poor parking job.'
Whoa - someone needs to take a chill pill.
