It had all started seven years ago, on Lily Evans' first ride on the Hogwarts Express.

Lily and her new found friends, Jess and Phoebe were sitting in a small compartment chatting excitedly about their new school. Lily was fascinated by the very idea of magic-coming from a muggle background Lily often found herself wondering if the letter, the visit from the ministry official and her trip to Diagon Alley hadn't all just been a very elaborate dream.

"Well I'm going to Gryffindor, where dwell the brave of heart!" Jess said loudly, interrupting Lily's thoughts and almost whacking Phoebe round the head with an imaginary sword.

"Watch where you're swinging that thing missus!" Phoebe scolded her, though unable to fully hide her smile.

"What about the other hou-" Lily began before she was interrupted by the arrival of three boys bursting into the compartment, laughing raucously having just set off a number of dung bombs in the corridor.

"Did you see the look on Snivvilly's face? Priceless!" Gasped one of the boys, running his hand through a mane of thick, curly black hair.

"Quick thinking using that slime spell your cousin taught you, Sirius!" Exclaimed a boy who, upon catching sight of the girls, ruffled his shorter black hair, giving him an even more windswept look.

"Stop being so vain, James!" The third boy laughed, not even attempting to smooth down his own sandy locks.

"Get out." Lily said firmly, having finally recovered from the dramatic entrance.

"You know what? I don't think we will." Huffed the boy who answered to 'James'. Lily's eyes glowed with indignation. No one spoke to Lily Evans like that.

"I said Get. Out...NOW!" She said through gritted teeth. Redheads sure had fiery tempers...

"Alright alright, don't get your panties in a twist!" James shouted back before storming out the door, swiftly followed by the other two.

"Really! The nerve of some peo-" Lily was once again cut off by three streams of green slime splattering the compartment and covering the disgusted girls.

Unfortunately for them, the boys quickly made it an annual tradition to prank the girls, adding fuel to the girls' hate.
