Pablo Neruda wrote clearly states that he is going through tough times in his poem "Your Laughter". However, the company of her beloved partner is his source of comfort and motivation. it is the reason why he keeps his own laughter.
The greatest source of joy he has is when his beloved partner laughs, as it reminds him of "the blue flower". The Rose from his echoing country. This is Neruda's reminder in the poem of his love for his country and culture.
