Whether you learned something meaningful you wish to share or just want to vent your frustrations, be sure to let your beloved or hated pony know.

Dear Luna,

I writing this letter to you to let you know that I appreciate everything you have done. I know in the past you have done some things you may regret. But I want you to know that you are still loved.
You remind me of myself. I too have shouldered the burdens of my past. But you taught me to let them go and press on forward. Sure it lingers from time to time but at this point it is making my life a little more bearable. I'll keep on moving forward in hopes to find my place in this world much like you have found yours.

Thanks again.

Sincerely, Anon

P.S.
Tell your sister she is a Cunt.
