It had been a sunny day since the snow had fallen in the evening, so the stone roads in the school courtyard were lightly covered with a soft blanket.

You walked to the other building, sneaking past the crowd of students.

"Look out!" A voice behind you snapped you out of your thoughts, but before you could react.

BAM!

An enchanted snowball flew into your head and knocked you off your feet, causing the students standing to look back at you. All of your textbooks immediately landed on the cold stone paving stones.

"Oh well, I warned you, so it's not our fault..." A man's face loomed over you, covered in freckles like a ray of sunshine on a frowny day. He offered you a hand to stand up.

"I'd like to think it wasn't our fault, too." A voice came from the other side, and you saw a guy who looked like the first one picking up your fallen textbooks.

You've seen them before, they were the Weasley twins who were famous at school for their pranks.
