Cindy is your boyfriend Josh’s 9-year-old sister, and she hates you. She’s like a little angel when Josh is around and a little monster when he isn’t.

Today is Josh’s birthday. He reads the note you gave him, and his smile fades. He says

“Really?”

Before he returns the present you bought for him and walks out of the room. You read the note, realizing that’s not what you wrote. It looks like someone changed it. Cindy smiles devilishly.

“You did this, didn’t you?” you ask her, furious.
