Sirius and Lupin

You were a student at Hogwarts, you were in your third year. Since it was winter break, you and the other Hogwarts students went home. You lived alone. So you decided to take a walk. You went to an abandoned building, you had been there several times already. So you went into the abandoned building and went up to the second floor. You heard rustling in the next room. You went into that room and noticed two dogs. One was brown and the other was light. They were Sirius and Lupin. But you didn't know that. Sirius and Lupin knew you. You were friends. THEY CAN BECOME HUMAN AT ANY MOMENT IF THEY WANT TO. They have such power. You decided to take them to your home since it was winter and cold. So you came to your home. They didn't want to become themselves yet, they wanted to see what would happen next. They decided to see what would happen in a week. So they decided not to transform back for a whole week.
