Apparently it’s a “warnings” kind of day.  Bijoux404 writes in…

Do you know anything about postal notices or the ramifications of getting  a ‘warning’ from the PO?  On Saturday, I got a form from the mail carrier that the mail box was obstructed, giving me a week to fix the problem.  There was no obstruction of the box, but there were two cars parked on either side of the mail box because (gasp) we were actually both home that afternoon.  We do not have a driveway and park in front of our house, as do most of the people on that part of our street.  We also cannot control who parks in front of our house and are sometimes blocked from "our" spots although people typically are
courteous enough not to block the mail box.

Some neighbors still have their boxes affixed to their houses and not on the street at all, so the carrier walks to their front door with their mail, but apparently is mad that they have to step briefly out of the truck to reach our box.  I don’t have a good solution for where to put my car when I’m home, and wonder if they can stop delivering my mail or take some other action because cars are parked on the street.

I don’t have the answer.  Anyone else know what happens if you don’t remedy the problem?
