Looks like Avon knows a fellow kid when she sees one!

New theory: Avon rang that doorbell herself. She took one look at your place and thought, "Now, there's a great place to stay! They'll love me, and feed me, and provide me with children to entertain me, and shelves to climb on, and plants to curl up in..." So she got a good running start, took a flying leap, crashed squarely into the doorbell, and proceeded to make herself look as pitiable as possible before you opened the door.

Kidding, of course....
