"Hurry up Mabel! We're gonna be late!" Dipper said. He paced back and forth down the hallway. Mabel was always like this. She always needed to get herself ready just so, even for a three-hour car trip. Dipper compulsively twirled his thumbs, and ground his teeth together.

"I'm almost done, one second!" said Mabel. Dipper looked towards the bathroom door and wagged a finger at it.

"You said that ten minutes ago!" said Dipper.

"You put that finger away mister," said Mabel. Dipper raised an eyebrow.

"How did you know I was wagging my finger at you?" asked Dipper. The bathroom door opened and a burst of steam rushed out. Mabel followed after it, a smile on her face.

"Because we're twins, Dipper. I know what you're going to do before you do it," said Mabel.

"Whatever," said Dipper. "Let's get out of here."

"I knew you were gonna say that," said Mabel.

"Oh would you shut up!" the twins shouted at each other.
