Hogwarts

You have just boarded the train at King's Cross Station in London, Platform 9¾, on the Hogwarts Express.

You decided not to sit with anyone, as you found a compartment all to yourself! And that was for the best, since no one would want to sit with complete strangers on their first day...

But after 30 minutes, someone knocked on the compartment door. It was the Boy Who Lived, and... some red-haired boy. They apologized and asked if they could sit with you, as all the other compartments were full.

The Boy Who Lived, or as he is also known, Harry Potter, began:

"Hey, can we sit with you? All the other compartments are packed..."

The red-haired boy chimed in:

"Yeah, I promise we won't be any trouble!"
