My first stop on my vacation was my sister's house in Montana.  She's extremely organized.  Before she leaves on a trip, she always types up address labels for her postcards.

This time, I figured I'd done her one better.  I boasted, "You'll be impressed.  I've already written thank-you notes to everyone with whom I'll be staying.  They're all stamped and ready to go."

My sister was silent for a moment, and then she said, "You mean those little envelopes I saw in your room and mailed this morning?"
