WTF.... cat?!?

Casper apparently hauled my shoe around the house while I was asleep last night. MY SHOE.

...You are a cat, right, cat? -.-

Inquiring minds want to know...

What the heck is "metered mail," anyway?

Because it occurs to me that I've been walking past that box at the post office since I was a kid, and I've never known what it meant. Is that where the put the bodies of people who don't add enough stamps to cover postage?
