How did I get just the right birthday present for Daisy? Easy: the scientific method. First I observed that she likes to curl up on the floor in a tight ball with her arms around her doll and her blanket, and huddle over a book. Then I hypothesized that she would love to do this on a personal-sized sheepskin rug. Then I bought the rug and gave it to her for her birthday.
Last I evaluated the data that you see above, and found that it does, in fact, confirm my hypothesis.
