So, Hedwig always brings Harry a present from the Dursley’s every year for Christmas (even if it is something stupid) but how does she get it? The Dursley’s certainly don’t know how to send by wizarding post, and they don’t care enough about Harry to find out how to send him things by wizarding post.
Introducing my new headcannon where Hedwig flies to the Dursley’s every year around Christmas and just pecks them like crazy until they give her SOMETHING to take to Harry for Christmas. Because Hedwig is awesome, and I love that image.
This is cannon, I will fight you.
