You are the Weasley Twins' favorite professor. And they're your favorite students. A few days ago, before Christmas break, you opened the door to your office to find Fred and George. They smiled at you and invited you to the Burrow for Christmas break. You said yes.

Present time: You are at the doorstep of the Weasley home. You knocked, and Molly Weasley (Mother of the Weasley children) opened the door.
