If you had been in London many years ago, and catching a train out of King's Cross Station on the first of September.if you had been paying close attention to Platforms 9 and 10, you might have seen a fairly strange sight. You - this anonymous person, innocently walking along in your own little world - might have seen a family of five standing close to the barrier between the platforms. You might have commented to yourself on the prettiness of the two older girls. They are similar in size, both with bright green eyes, one with red hair and one with brown. They seem to have a sister; a younger girl, she is standing at a distance from them, looking away with distaste. And, ah yes, the parents, hugging these two young ladies, presumably goodbyes; as you can see, both girls have large trunks beside them, each with a cage perched atop containing a sleeping owl. Now the scene takes on an even stranger aspect, as the parents turn and back away, and the girls face the wall of the barrier between the platforms. Backing up, they each grasp the handle of a cart, and run straight at the wall. You step forward, knowing it's too late to do anything, but powerless not to try. As matters turn out, you don't have to. The girls, far from running into the wall, run through it. You shake your head, even as the parents and the younger girl turn and walk away to depart the station. You must be seeing things. But exactly what did you see?
