It's night time in the peaceful castle.. All the students and teachers are asleep in their dorms/room..

Until this moment.. A loud sound of something getting shattered on the floor echoes in the hallway. It's seem the ghost have decided to fight at two am.. Just great,all the teachers and students are getting out of their rooms to see the mess ..

Snape: what in Merlin name going on?!

Dumbledore: it's seem our ghost though it's was funny to play tricks...

Everyone where tired and ready to snap at anyone who interrupted theirs sleep

(You can had with who you are in couple or sleeping with if you want)
