The musty air of the attic invigorated Chloe. She bounded up the stairs, her feet barely touching the treads. She had been dying to see what she could find. This was her favorite kind of activity. Her eyes sparkled with anticipation.

She spotted a trunk, its leather straps cracked with age. She pried it open and peeked inside, gasping at the contents. A collection of old costumes! A pirate hat, a feather boa, and a sequined dress. She instantly threw open the lid and began rummaging through the items, holding them up and admiring her reflection in a nearby mirror.
