  "Mr. Potter, here is your schedule," Professor Snape thrust a piece of parchment into the young boys hand before walking off. Harry didn't know why Snape didn't like him but then remembered what Kingsley had told him. James Potter bullied Severus Snape a lot in school, not that Severus was entirely innocent either. Snape had more than a few times gone too far in getting revenge and openly attacked James as well. He had also said something to Harry's mother but Kingsley never told him what. Both continued to go at each other and still, to this very day, hate each other.
