I need help analyzing themes and how poetic devices add to the thems of the poem "Clouds."explain themes and metaphors etc. and at least two poetic...

In "Clouds," the poet W. Symborska uses a kind of
negative personification a number of times in his descriptions of clouds.  In other
words, the poet describes how clouds do not act like
people. 

The clouds "don’t repeat a single shape, shade,
pose, [or] arrangement."

The clouds are "unburdened by
memory of any kind."

They "float easily over the facts" and
cannot "bear witness" to anything.

The poet also compares
clouds to a "haughty fleet" of ships that "cruises smoothly over your whole
life."

The poet seems to be using these metaphors and
personifications in order to reflect on the very different nature of human beings.  In
contrast to clouds, humans are burdened by memories; they bear witness to, and are
affected, by many different events; and they do not "cruise smoothly" through
life.
