3 boys in a closet

We rode the train to visit cousins at the hospital yesterday. Ethan, Nate and Samuel were a riot. At least it sounded like a riot. A magic wand turned them into various animals, but they hid in the closet to avoid being turned into a bowl of oatmeal or a fairy princess. They rode in cars up and down the hall, giggling and squealing all the time. As we left (through a different door than we'd entered) I looked back and saw a sign on the door that read "Quiet, entering research area." Oops. Too late.
