Today was a particularly boring day for Danny. All day long something had been bugging her, and like usual she refused to tell anyone what it was. It wasn't like she trusted anyone in this school to tell them what was on her mind. It just wasn't like her. Finally, though, her classes were over and she finally had time to think about what was going on in her life. Her brother was getting married soon, and it asn't to that Hufflepuff girl he liked so much. It was to another pureblood girl, who was also in Slytherin just like the two of them. Her name was Amy something... Not like it mattered to Danny. What bothered her is that she would, one day, have this happen to her. She would have to marry another pureblood even if she didn't like him.
Sighing as she walked to the lake, Danny spotted a girl sitting under a tree near the lake, and her usual devious smile came onto her face. Finally she would get to have some fun, something she'd been wanting to do for a while now. And this time her brother wouldn't stop her, because she wasn't pranking the girl he loved. This time she was free to do as she pleased. Anyway it didn't look like her brother was there anyway, so she didn't worry about him. With the same smile on her mouth, she ran toward the back of the tree where the girl sat, and she climbed with ease. To anyone who didn't know her it would sound like a bird or something landed in the tree and they wouldn't suspect anything.
By the looks of it this girl was younger than her, and she was sure she was weaker than her. The girl's clothes told Danny that she was a Ravenclaw. Her other favorite house to prank. This girl's reaction wouldn't be as funny as a Hufflepuff's reaction but it would do, to satisfy Danny's need for pranking. Slowly and crawled out onto a branch that was just over the girl, and she swiftly pulled out her wand. Smirking and the shadows covering her face from her nose up, she whispered, "Augamenti." Sending a small jet of water from her wand onto top of the girl's head.
