I’ve started calling Isabella Mrs. Tittlemouse, after her favorite Beatrix Potter character. This morning offered up a classic example of her extreme tidiness. I’d given her some slices of cheese in a plastic bag and when she finished them she went to the kitchen garbage can to throw the bag away. But she discovered that I’d taken the trash out to the curb this morning and forgotten to put a new trash bag in the can. So she headed to the shelf by the door where we keep the trash bags so she could get a replacement bag before she threw away her trash. I found her there tugging a bag out from the box.
