USPS, your fu is weak! You must train harder. (But Emma's happy so it's okay.)

Update at 6:10 pm: Okay, now I'm happy. So my mood icon has been altered to reflect my no-longer-dissatisfied state. ^_^

I went to track Emma's package on the USPS web site. And what did I get?
"There is no record of that item. If it was mailed recently, information may not yet be available. Please try again later."

Those lamers. I mailed it on Monday. Monday! They can't enter it into the system inside of four working days? Grr. >:(
