This question was surprisingly very hard for me. Hermione, Harry, Ron, Dumbledore, and Snape were people that I first thought of. Then the Weasley twins came into mind, and I knew that's who I wanted to take to the ball. Now don't make me choose which twin, that's cruel. Going to the ball with one of the twins is something I image to be a blast. They are both so hilarious and fun! It would be night filled with laughs and memories , that's for one. I mean if I could, I would take both to the ball. ;)
