That the postal service decided to deliver my packages to three different pick up points instead of just the same one. 
I've had packages end up delivered at the wrong mail box once or twice. I literally had to walk up to a neighbor's porch once to get my package off their doorstep because it wasn't theirs.
This has happened with both USPS and UPS! I've also had neighbor's packages in my mail before. I walked aaaall the way down the street just to put it in their mailbox, haha.
If anything keyboard related ended up in the wrong mail box, especially something small (like that DTA clack, for instance), which would undoubtably be thought of as a worthless trinket. I would die. Right there. Dead.
C'mon, youspse and oops, get it together!
