About three blocks down the street, we have a mailbox; squat and blue, it stands in the middle of a block. About ten yards behind it, there's a parking lot. Most (considerate) people pull in to the parking lot and walk back to the box to deposit their outgoing mail.
However, asshats abound.
A couple of mornings ago, I found myself stuck in the middle of a line of traffic, waiting for someone who had stopped dead in the middle of the street, turned on their flashers and was depositing their very large stack of mail -- one piece at a time. He'd pick an individual envelope, scan the front and back carefully, put it on the mail chute/flap, close it and then re-open the chute to make sure that the piece had slipped down into the box. He did this with about twenty letters.
Meanwhile, traffic behind him was building up, and the cars in the opposing direction were too numerous to allow anyone to pull out and pass the offending idiot. Predictably, the honking began and was a deafening din in no time at all. This did not encourage the letter-mailer to move any faster. Eventually, he finished his stack, went back to his car and drove off...
Only to be replaced by another idiot three cars later, who did the exact same thing.
