The bear stared back at Amelia from the cluttered yard sale table. A surge of exhilaration coursed through her, the kind she remembered as a child just before a particularly thrilling roller coaster ride. She remembered the secret language she and the bear, Rupert, used to share. It was as if she could hear his silent greeting.

She rummaged through her purse, eager to make the purchase, imagining all the crazy things they could do together. She could hold tea parties, tell ghost stories. She could do the things she had always done.

Back at her apartment, she started playing her favorite childhood music, the kind that always made her want to dance. She pulled Rupert close and started to waltz around the room.
