Letters to Someone

Letters. The most nostalgic and romantic place for words. They are exact what it's says in the title. They are letters, written by different people about different relations to special someones. These don't apply to the public. They were written with purpose--addressed to certain people.
This is not displaying how every relationship of that title looks like.
It's raw, honest, heartwarming, heartbreaking, confusing, maddening,
But then again all these feelings are valid.
I'm the end one has to bear that in mind.
