The original question had to be edited. The speaker is a child who goes to school and seems sincerely fascinated with the world around them. In this light, one can see that there are profound implications about how any vocation, when viewed through the lens of pure optimism, can contain elements that individuals can find liberating. The bangle seller is representative of freedom in mobility and schedule. The gardener is able to be as dirty as possible and is able to remain outside without reproach from anyone, while the watchman is able to embody the freedom to "chase shadows."
The implications of the speaker's understanding in each vocation represents much in way of redemption. The speaker is not deterred by the professions and their potential downsides. Rather, these affirmative notions of the good enhance how there can be hope and happiness in any vocation. The sincerity with which the speaker views these professions helps to display how all work has something within it that can affirm one's being in the world. The implications of this revelation help to underscore how work, in its most intrinsic form, can be seen as good.
