literary interpretation

Close read of Pablo Neruda's poem:
Pablo makes his message clear. There once was happiness in his little Spanish town where happiness blossomed in every cranny of his house... When he says "Remember Raul?" It's like asking someone to remember a better time... hey, remember when...
He speaks of Raul, Rafel, and Federico as though they are dead... "The light of June drowned flowers in your mouth..." That line makes me think that they are buried, and in need of being remembered.
The basic feel of the beginning is of home, toasty and comforting--then the planes come and childrens' blood fills the streets... and the good feeling is definitely gone.
