A mischievous glint sparkled in Maya's eyes as she sauntered into the room, her backpack swinging carelessly. She'd spent the afternoon replacing all of Ben’s pens with glitter pens. The desk now looked like a unicorn had exploded. And just for good measure, she’d neatly organized his books by the most absurd categories she could think of: ‘Books I Pretend to Read,’ ‘Books That Smell Like Grandmas,’ and ‘Books That Judge You.’

The corner of her lips tugged upwards as she grabbed a brightly colored marker and began sketching a silly picture of Ben on the whiteboard, complete with bunny ears. This was going to be an amusing evening.
