Harry Potter has always been a resourceful wizard, but there's no denying that he wouldn't be nearly as successful if it weren't for his friends and family. Before he went to Hogwarts, he only ever had two real friends, Hagrid and Ron Weasley, both of whom he met as soon as he was exposed to the Wizarding World. However, even though these were the only two people he befriended before attending the magic school, Harry always had people watching over him. In fact, those same people may have helped make the Weasley family the most important people he would ever meet.
