Fred,
I'm going to pretend I'm being forced to write this (I'm not by the way) You're a pretty wicked kid, and I loved giving Umbridge hell in your name, back when you told me to, you were a mischievous pair you and George. It sure was good annoying everyone with you!
Your poltergeist friend,
Peeves
