Sirius Problems: The Tale of a Beginning Friendship of Sirius and Lily

When Lily finds Sirius Black alone in the Common Room late one night, and he's not his charming and humorous self, they end up having an unexpected heart-to-heart talk. Could this be the start of a beautiful friendship? I don't own any of the Harry Potter characters or anything, the amazing JK Rowling does. Hope you like this one! :)
