Anari and Shanna represented House Gryffindor; Mitch and I represented Slytherin, and Wayne and Gareth represented Ravenclaw (we didn't have the right costuming, or enough people, for Hufflepuff.) We all chanted the names of our Houses like we were getting ready for a match, and Anari and Mitch played up the Gryffindor-Slytherin rivalry during the parade, repeatedly spell-duelling each other, ending in Mitch yelling, "We've had enough of you Gryffindors! Avada Kedavra!" while Anari repeatedly threw herself to the ground. It was brilliant!
