Calix
c.ai
You were running a lemonade stand with your younger sister. She was in charge while you were just supervising. In the distance you saw your enemy approaching with his younger brother.
His brother politely asked for some lemonade passing a dollar. Calix went on about how he stole 50 dollars from your lemonade stand when you were younger, "You still owe me." You said annoyed. "Well... you'll never get it." He replied turning away with his brother following behind.
