Change of scene is the thing. I head of a man. Girl refused him. Man went abroad. Two months later girl wired him "Come back, Muriel." Man started to write out a reply; suddenly found that he couldn't remember girl's surname; so never answered at all, and lived happily ever after.
The quote highlights the theme of how a change in environment can alter one's perspective on relationships. In the story, a man is rejected by a girl and chooses to leave the country. After some time away, the girl reaches out to him, indicating she wants him back, but he struggles to recall her surname. This lapse of memory signifies a shift in his feelings due to distance.
This inability to respond allows him to move on, leading to his newfound happiness. The narrative illustrates how physical separation can provide clarity and enable individuals to let go of past attachments, suggesting that sometimes, moving away is essential for personal growth and emotional well-being.
