Mary Ostergren is a high school sophomore in St. Paul, Minnesota. I’ve known her since the day my sister gave birth to her. When Mary was a little kid, her puppet-crazed auntie (me) gave her a cow puppet. Then Mary gave me a cow puppet. So we have matching cow puppets. Hers is Daisy. Mine is Butterfat. A number of years ago, my former student Jarrad asked me to give him a writing assignment. I told him to write a sonnet, and I would, too. I looked around the house for something to write a sonnet about, and I found Butterfat. I can’t express how proud I am of my niece, who, in addition to having a great voice, is a reader of challenging books, a hiker of trails, a connoisseur of both dresses and ice cream, an incredibly fast runner, a wrestler of complex ideas, and a fun person to have around, among many other things. We recorded her in our kitchen.
