Oh! Well, this cannot be right. I should be walking into my Arithmancy class... not down some London street!
Ok, I just need to regroup and figure out what just happened. I - I most obviously did not disapperate out of Hogwarts, nor did someone take me on a side along disaperation - I cannot do it myself, nor can anyone disapperate or apperate onto the grounds at Hogwarts... so that leaves... It could not be dark magic as there is no way one of Lord Voldemort's followers could have got inside Hogwarts, could they?
And what is this muggle device?
Harry? ... Ron? ... er, what just happened?
