DZ:
Seems that you didn't have enough postage on the last package you sent (you out of the mail room) and you got returned to sender.
If you promise to be nice to AU until at least noon today, I'll give you back one star which I took away. It should be enough postage to get you back on your way out of the mailroom.
NOTE: Please read this as a joke, I see that you did wish him well at the end of your msg, I am still trying to game out how these stars and posting counts equate to your overall score, got you currently as a 4 of 5
