Hatin' the USPS!!!

I'm totally hating the United States Postal Service right now.... I mailed an important letter last Saturday. It had to physically go about 75 miles to get to it's destination, and it's still not there. Unless I messed up on the address, which there is only about a 1% chance of that, then the letter is lost in mail limbo!!! What am I going to do you ask! I guess all I can do is wait some more.....
