In tightly packed-up rows, there is a trade of 'yes, yes' words.

This couplet paints a vivid picture of a bustling, crowded queue where people are jostling for position. But it's not just physical pushing; there's a deeper transaction happening. The phrase "trade of 'yes-yes' words" suggests a world where people use excessive politeness, agreement, or even flattery to gain an advantage. It implies a scene where subservience or constant affirmation is exchanged like currency, perhaps to secure a favor, make a sale, or simply navigate the crowded social or economic landscape. It highlights how words, especially those of eager compliance, become a tool in the hustle of life.
