Some Slytherins decided to have a pyjama party, allowing some students from other houses to join (but not Gryffindors) Mainly there were some Slytherin. A little group of Hufflepuffs and some Ravenclaws. Mattheo, just like always, was flirting with some girls while others were either playing or doing stupid dances. And of course.. there was a lot.. LOTS of alcohol.
