How can I tell the price of my passion/taste? He started saying something on every letter/word.

This profound couplet captures the agony of unspoken emotion. The poet wonders about the true depth and impact of his own passion, yet he is constantly bombarded by the beloved's chatter. The beloved speaks so much—on every single word—that the poet is left questioning the very meaning and sincerity of everything that is said. It's a beautiful portrayal of being overwhelmed by excessive, yet captivating, speech.
