While The children of the famous Harry Potter have already finished their last years of school, a new bunch of children, like every year, arrive. And I'm in the 'bunch' this time. Gryffindor, Slytherin, Ravenclaw and Hufflepuff, the four houses of Hogwarts, School of Witchcraft and Wizardry. I was sorted in one of them of course, and so were my best friends. But we were each in a different one... And believe me, THAT creates problems!
