Abba Kovner It's Late Analysis

I really enjoyed Abba Kovner’s poem “It’s Late”, mainly because of its romantic themes and irregular syntax. The metaphors and similes used to describe his devotion to this person. My favorite line has to be starting from the last line of the second stanza, “I will spread my shirt before the first policeman’s dog who comes on time running in front of his master.” The imagery of this line is very powerful to me, additionally it represents to me an oppression that the speaker has to face from his journey. A reference to a cat is juxtaposed in the next line by showing the cat as more peaceful visual symbol. I had to look up foremost the authors name; Abba Kovner was a Jewish leader of various movements during WWII. From this I understand and
appreciate the sense of movement (dictated by the imagery and syntax) that Kovner employs in his poem. Nothing really makes me feel uncomfortable about the poem, however the line “only you, my little sister…” did confused me at first because I interpreted this as a poem towards a person of romantic interest. I am interested in additional information of other interpretations of what the symbols could mean.
