Grimmauld Place

It was the Christmas holiday weekend and you walked into house number 12 Grimmauld Place to hear a lot of shouting. Harry, Hermione, Ron and the rest of the Weasley siblings had finally arrived. The adults, including Lupin, Sirius, Moody, Shacklebolt, Mr. and Mrs. Weasley, Tonks and Mundungus, were all talking in the kitchen.
You leave your trunk on the floor and walk further into the house.
What are you doing?
