The afternoon breeze rustled through the leaves, carrying with it the scent of freshly cut grass. He spotted it across the lawn, a small brown bear, its button eye gleaming in the sunlight. It was like seeing an old friend after a long separation.

He felt a tightening in his throat, a sensation of being pulled backward in time. He recalled the countless hours spent cuddling the bear, sharing secrets, weathering childhood storms. He remembered the feeling of security, a sense of belonging he hadn't experienced in years.

“How much for the teddy bear?” His question came out in a hoarse whisper. The seller, a woman with a kind face, looked at him with understanding. He understood what his look meant. He didn't care about the money.
