Staring at a blank piece of parchment for an undetermined period of time was probably one of Ron's stupidest ideas. He was completely baffled with what he was supposed to be doing - as he hadn't been paying at all - and when he'd asked Hermione for help, she'd turned him down with a scoff and a roll of her eyes.
She never turned him down. He didn't know how to do homework. He didn't even know what a Gibraltar Campion was let alone what assignment he was doing.
And now, two hours after he began the task of staring, Ron was confronted with a beige overload. Everything he looked at, everything he touched, turned to beige. His skin. The wooden table. The couch. Harry's hair.
It was a disaster and he was going to go crazy if he kept this up! He didn't tell anyone the problem however, instead choosing to bash his head against the beige table multiple times, oblivious to the weird looks he was getting.
He didn't want to bring anyone else into the world of beige-ness.
