Hogwarts: An Adventure

You wake up in your bed. You hop out and start putting on your clothes. You're excited because you've just been excepted into Hogwarts School of Witchcraft and Wizardry. You hurry downstairs, make a bowl of cereal, and go over to the refrigerator. You pick up your shopping list and look it down. You take it with you, and hurry out the front door to your friend, Quint's house. Your parents said it was okay to go shopping with him and his family. Your twin sister, June, follows you out the door. Your parents forced her to go with you so she makes sure that you don't get into any trouble. You arrive at Quint's house, and he lets you in. A few hours pass, and Quint's dad whips out a bag of Floo Powder. Quint grabs a handful of powder and hurries into the fireplace. He shouts out, "DIAGON ALLEY!" and disappears in a cloud of green smoke. Who goes next?
