“And he remembered my birthday!” Mark's voice boomed across the crowded restaurant, a jovial laugh punctuating the sentence. Daniel found the noise grating, a physical discomfort he couldn't shake. He’d eaten a large meal, and the warmth of the food was now a comforting weight. He had difficulty staying upright. The tablecloth blurred slightly.

Daniel blinked rapidly, the details of a previous date flooding his memory. It felt… off. He needed to think, but it felt like a monumental task.
