"Life isn’t fair"

Severus Snape

Both Sirius and Fred, Hogwarts pranksters, died laughing.

Only one couple were still battling, apparently unaware of the new arrival. Harry saw Sirius duck Bellatrix’s jet of red light: He was laughing at her. “Come on, you can do better than that!” he yelled, his voice echoing around the cavernous room.

The second jet of light hit him squarely on the chest. The laughter had not quite died from his face, but his eyes widened in shock.

"Ofcourse it is happening inside your head Harry, but why on earth should that mean that it is not real?"
