The quote reflects on the nature of life and death, emphasizing that when a man passes away, it's merely his presence that is lost. The speaker acknowledges the practical role a man plays in a family, such as providing and protecting, but suggests that any decent man is capable of fulfilling that role. This implies a certain interchangeability among men in these societal functions.
In contrast, the quote presents a woman's life as profoundly impactful and unique. The idea that "a woman takes life with her when she goes" suggests that a woman embodies a rich potential and influence, far beyond what can be measured by her conventional roles. The fleeting smile adds a personal touch, indicating a deeper, perhaps more emotional connection to the idea of femininity as a source of infinite possibilities.
