Melissa sat on a bench outside school watching the buses pull up to the curb. The door of the first bus opened, and her friend Caroline stepped off. Caroline walked over and stopped in front of her. Melissa looked down at the ground and pouted.
Caroline put her hands on her hips. "What's your problem?"
"I'm just having a bad day," said Melissa in a grumpy voice.
"You don't remember, do you?" asked Caroline as she sat down next to Melissa.
"Remember what?" Melissa asked puzzled.
"Today is The Great American Grump Out. Don't you remember? We talked about it last week," said Caroline.
"Oh, I forgot!" said Melissa, putting her hand to her mouth.
Caroline frowned. "You just can't be grumpy today! We're supposed to pass out smiley face stickers and encourage everyone to be cheerful. You're going to ruin it if you can't smile."
Melissa giggled. "Now you're the one who's grumpy."
Caroline let out a yell and then started laughing. "It's all your fault!"
