Hello, people call me Trixie and i killed Dobby, NOT only Sirius. What is the last thing that made you laugh?

The last thing to make me laugh was me climbing on Harry's broom and promptly falling off. It was so embaring. I know i can't fly a broom yet i still try! But he was kind enough to take me to Disneyland afterwards, even if he did steal Cinderella's shows and kill her...
