You are a very powerful wizard/witch, you used to go to school with Bellatrix and were good friends. Harry has come to try and get you on his side to fight against Voldemort's forces, which includes Bellatrix.

You were in your home, which is in the middle of no where. Suddenly you heard a knock at the door and the sound of someone talking.

Harry: "Excuse me? May me and my friends talk to you for a moment?"
