Once upon a time there were two little kids named Sarah and Mack and they were best friends.  They’d known each other since they were three weeks old and they played together almost every day.  Their moms were best friends, too, and they both had curly brown hair.  All of Sarah and Mack’s playmates at their preschool couldn’t tell their moms apart.  Also, both of their dads played guitar and they had younger siblings who were the same age.  Next year, Sarah and Mack were going to go to kindergarten together.

One day, Mack and Sarah were playing at Mack’s house.  They had just finished lunch and they were arguing because Sarah didn’t like the way Mack leaned all the way over his bowl when he ate his cereal.  Mack said that Sarah was stupid because she always spilled food on herself because she didn’t lean over her bowl.  Mack’s mom said that they needed to do something more constructive and would they like to wash the walls in the bathroom?

Mack and Sarah got big yellow sponges and went into the bathroom.  Sarah started sponging the walls and Mack closed the door and wiped it down.  Then he got soap and put suds on the door handle, too, so that it was nice and clean.  Wouldn’t it be silly, he thought, if  he locked the door and he and Sarah couldn’t get out?  He locked the door.

“Look, Sarah!”  He said.  “I locked the door.  Now we can’t get out.”  

“Yes we can,” she said, “You can just unlock it.”  But she was secretly concerned, so she put down her yellow sponge and tried to turn the lock the other way.  It was too slippery.  “I can’t unlock it,” she whined.  She rattled the handle, but it wouldn’t open.  She dried her hands and tried again, but the door still wouldn’t budge.  

“You’re so stupid, Mack!”  She said.  “I hate you.  Now we’ll never be able to get out and we’ll be trapped in here forever.”

Mack grinned at her.  It was funny how Sarah got upset so easily.   He loved it.  He knew that his mom would get them out.  He snickered at Sarah and sat down on the rim of the bathtub.  

“Haha we’re trapped and now we’ll never get out and we’ll have to live in here forever,”  he taunted her.  He hoped his mom would hurry up and let them out soon, because he was secretly getting a little nervous.  

Sarah yelled for Mack’s mom, but she was outside gardening, so she didn’t hear.  Sarah and Mack tried to dry the door handle, but the soap wouldn’t come off.    Mack’s mom had forgotten about them.  

One day, many months later she had to use the bathroom, and was surprised when the handle wouldn’t turn.  She fetched a screwdriver and removed the handle.  She found Sarah and Mack inside.  They were very hungry and very upset, but they were happy to finally be out.  Mack’s mom gave them cereal and they didn’t argue once about how to eat it.  Then Sarah went back home and her mom was so happy to see her.  She had just been thinking that morning  that she should call Mack’s mom and see if she’d left Sarah at Mack’s house.
