Dear Mr. Postman --
I'm not quite sure what you're doing delivering packages on a Sunday afternoon. But my soon to be two-year-old nephew will appreciate your hard work when his Cool Aunt shows up at his birthday party Tuesday night with the present she was hoping to give him and not some alternative, or worse nothing.
Amazon.com may think it's OK for packages to take side trips throughout the city of Philadelphia or the mail facility there, but I'm glad the folks at the United States Postal Service realize the importance of customers getting their packages on time.
The Aunt who will now be cool because Ice Age: The Meltdown has arrived.
