In a harry potter quidditch match fanfiction, it could start like this. The day of the big Quidditch match had arrived. The stands were filled with excited students from all four houses.

But Hufflepuff's Beaters were not to be underestimated. They managed to keep most of the Bludgers away from their team. The Seekers were waiting for the right moment.
