Harry Potter and the Sorcerer's Stone (Re-Write)

You know how the story goes: An 11 year old boy finds out that he's a wizard from a friendly, lovable half-giant named Hagrid, Hagrid tells Harry what happened to his parents and who Voldemort is, then Harry begins his journey to Hogwarts, but the story changes after Harry befriends a pair of wizards starting at Hogwarts also. How will their meeting change this story?
