The speaker expresses a profound sense of sadness that seems to be a constant part of their existence. They ponder whether this perpetual state of sadness actually means they are not sad at all, suggesting that true sadness is a deviation from one's normal state. This leads them to a contemplative realization that their ongoing demeanor might indicate a unique emotional steadiness.

This reflection may suggest a deeper philosophical inquiry into the nature of emotions and individual perception. The speaker entertains the idea that their unchanging state could mean they have a kind of luck, as they might be alone in never experiencing the fluctuations of sadness that others do. This complex view challenges the conventional understanding of emotional responses and highlights the intricacies of human feelings.
