The quote reflects a seemingly mundane conversation where two individuals exchange simple pleasantries about their whereabouts and the weather. The dialogue emphasizes a lack of depth and meaningful connection, as they discuss trivial topics without engaging in deeper issues or emotions. It portrays a sense of disconnection in their interaction.

Instead, it results in just a "cairn of a lost conversation," suggesting that their words, though they exist, do not contribute to building a strong relationship or understanding between them.
