Dear Harry Potter,
You are by far the most sassy yet bitter person I have ever encountered. Despite these qualities, you are one of the best heroes I know. Your influence will never die away.
P.S. What in the world were you thinking when you named your children? Do you know the amount of teasing they are gonna face?
See you guys, it is as simple as that. The letter can be long, it can be short, it is all up to you.
