The online ad showed the house. His house. The old brick facade, the crooked chimney, the overgrown rose bushes his mother had always fussed over. A wave of warmth spread through him, making his cheeks flush.

He immediately picked up his phone, already envisioning himself walking through the front door. "Mom? You won't believe this," he practically sang into the receiver.

He was already mentally arranging the furniture, picturing himself in the sun-drenched living room with his favorite armchair. The thought sent another surge of joy through him, so potent that he felt he might float.
