Not impressed with my mail carrier. I know mail boxes belong to the post office but this is not right. A package was delivered that was to big but was shoved into the box. It took us almost an hour to get it out. Do you not bring bigger packages to door, if it doesn't fit? We try to keep our area nice but apparently our mail person can't read and writes the number on the box itself, it's clearly marked in both sides of the poll. I even wrote a note and left it on the box stating so.
