Sarah and Will have been going through a cowboy/cowgirl phase lately. For like 6 months, really. I wanted to make them stick horses so they would quit trying to ride anyone or anything that stayed still for more than 30 seconds ("Giddyap, Daddy!" or "Hi-yo, Biscuit!", the 10 lb. she-poo that lives next door).
Sarah and I did establish that her unicorn eats fairy dust and carrots. ("Not rainbow dust, Mommy! You're so embarrassing!")
