Chloe typed furiously "Very clever" and then turned off her phone. She was so sick of her brother and his friends! They always pulled pranks on her. Today, as she opened her bedroom door, a bucket of yellow paint fell on her head. This was going to be the last time they messed with her. 

She showered and managed to get most of the paint out of her hair and then called Aiden Johnson, one of her classmates since nursery who, until this year as he'd quit, was the biggest pranker in school. He could help her prank them so hard, they'd never messed with her again.

"I'm done with pranks, Chloe. I've outgrown them."

"Aiden, I am begging you, one last prank! Just so my brother and his idiotic friends can stop messing with me!"

"Alright, on one condition: you owe me one."

"Fine."

Whatever he wanted could be dealt after James and his "boys" would stop messing with her. 

Aiden made up an evil genius plan. The boy attached buckets of glue to drones, made fish guts fall on the boys once they walked through the door and red paint run through the plumbery of her brother's bathroom.

"You are a genius." the girl said after Aiden's shown her his work.

"I know, but now all the geniosity will be used in physics, college in 2 years. Your brother and his friends are coming! Quick. Hand me the drone controllers when I tell you 'now'."

"Okay."

'Now' and a bucket of glue fell, 'now' and another one, 'now - just like clockwork, the last bucket fell. The three boys were covered in glue, they ran towards the door and as they tried to walk in the fish guts fell and stuck to them. 

Aiden and Chloe high fived and the girl said "How you like pranks now!", her brother yelled "Very clever!" and ran to his bathroom to clean up, "I'll shower first, just thumb war for who wants to go to the guest bathroom."

"3... 2... 1..." Aiden counted, then Chloe's brother appeared, painted in red. 

"I hate you, Chloe!"

"But I thought you liked paint, given the fact you put a bucket on my door to cover me in it."

He rolled his eyes and him and his friends decided to go to one of his friends' house.

Chloe cleaned up while Aiden repaired the plumbing.

"About that favour that you owe me... send me the answers to the chemistry homework until the school year ends."

"A fair price."

In the end, Chloe's brother stopped pulling pranks on her and Aiden always had his chemistry homework done.
