The protagonist experiences rare and unforgettable moments that leave a lasting imprint on his memory. Unlike ordinary experiences, these moments are distinct and vivid, allowing him to recall them in intricate detail throughout his life. Even amidst more intense experiences, whether beautiful or horrific, he finds that they do not stick in his mind as strongly as these unique instances.
He refers to these profound experiences as "still moments," as they abruptly surface without any preamble. They capture the essence of everyday occurrences, etching them indelibly into his thoughts, highlighting their significance in contrast to the fleeting nature of typical memories.
