I own nothing that you recognise as J.K.'s work
It was just another quiet day in the Gryffindor common room. That is until the sixth year girls came running in screaming, wearing blue pyjamas, all except one girl, Jane Lupin Remus Lupin's twin sister, she doesn't mind the colour blue, plus her pyjamas were the colour they were originally, light green.
The resultant effect of the screaming and shouting was that several boys in the far corner of the room started roaring with laughter, this then sparked two immediate reactions: the boy's started to run to the portrait hole with the girls in hot pursuit.
Sometime later the boys all returned, triumphant looks on their faces, the boys that were in the common room cheered them on.
"Well that was a good way to spend half the day." Lupin said with a massive grin on his face.
"I wonder how long it will take them to get us to change them back?" questioned Peter.
"They won't Evans will change them back soon enough, no they probably just wanted revenge on us." James stated coolly.
"Well then what can we do now?" Sirius asked a bored tone colouring his voice.
"Stay in now I suppose, not much fun in torturing the same people twice." James stated, also bored.
"I agree with James." Peter said at once
"You would do worm. How about we plan next month's stroll?" Lupin stated and then asked.
"Sounds like a plan moony" Sirius and James chorused, at which point both boys started laughing, followed by the other two.
They stayed up late into the night planning next month's adventure, when suddenly they heard someone come up the stairs; they immediately stopped talking and pretended to be asleep.
"It won't work I know you are up boys." Lily's voice sounded from the door.
"I just came in to let you know that I know Remus' 'furry little problem' and I also know that being unregistered animagi is illegal. I also wanted to ask padfoot when he is going to ask Jane out, it's obvious that you like her Sirius." She stated calmly.
"I'm going to state something now Lilly. But out of my business." Sirius growled, fury evident in his voice.
Lilly walked out of the dormitory laughing at Sirius Blacks reaction to her teasing.
Sorry I haven't put a lot more meat into the story but it is hard when you're revising for GCSEs, more will be said in chapter two please read and review.
