Organized

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?"
