"I'm so sorry! I'm so, so sorry.", cried Jessica

"Maybe next time you'll listen to me!", Lana yelled.

"I will!", pleaded Jessica.

"Promise?"

"Yes, anything you say."

"Where are you going?", asked Jessica

"To the lost and found."

"There's nothing there, I checked"

"Oh", said Lana, dejected, "I see. Then I guess I'm going to my next class. See you there..."
