I read a very good little wee!chester fic a few years back (before 2013 possibly?), I believe it was from fanfic.net but I can't remember the title or author. I only remeber a few details but I hope someone can help me find it, I would love to read it again. It wasn't terribly long and I believe it was complete. It was a short timeline or Dean remembering part of his childhood and everything he did and sacrificed for Sam. There was a part I remember clearly that Dean taught Sam how to shoot with his gun which he learned on and was given to him by John. I think it was kept in an old metal lock box. Dean was proud that Sam was good with it.

I know that it's all very vegue but I hope someone knows this fic and can point it out to me. Thanks so much.
