"Augghhh!"
Hermione slammed her book shut. Leaving Ron alone in the kitchen probably wasn't the best idea. This was the third yell to reach her, and they all seemed to come at about five minute intervals. This was the final straw. Ron had probably blown up the toaster or something equally stupid.
She arrived downstairs to find Ron sulking against the wall, glaring at the door opposite.
"Ron... what is going on?" she asked warily.
"Cookies... not working!"
"What do you mean, 'not working'?"
"I wanted cookies, so I decided to make some. They won't spread!"
Hermione frowned. Cookies were simple. "Well, glaring at the door isn't going to help. Let me have a look."
"Fine."
Hermione entered the kitchen, Ron trailing behind her. Hermione inspected the small piles of mixture sitting on the tray.
"They look fine, Ron. Just stick them in the oven."
"They haven't spread yet, Hermione!"
"What are you talking about? They don't need to spread."
Ron pointed at the instructions, and Hermione burst out laughing.
"Oh, Ron," she said through tears of laughter, sticking the tray in the oven. She left the room, still laughing, muttering "Honestly. 'Leave room for the cookies to spread'..."
Ron blinked. "What?" he yelled after her. "I did! Three times!"
This was based on something stupid my friend did while making cookies. Basically she saw the instruction saying 'leave room for the cookies to spread' and got really confused, thinking she had to leave the room so that they'd spread, and then I came up with this. Thanks Aims.
