when I first came to Hogwarts I was little upset and when I entered the Gryffindor common room I felt familiar with it which was most unnatural as I was entering this room for the first time in my life . then suddenly and most unexpectedly I had a vision I was in a tunnel which was full of snakes and suddenly a man appeared of nowhere and " what is your name , boy " and I answered that my name was tom riddle and I belong to Gryffindor . then the stranger said give me your hanky boy , give me your hanky and the vision ended .
