Social mores change all the time. In the mid-1970s, it would've been astonishing, say, to see two men holding hands in the streets. And the attitude to having a fling with a girl, or whatever, was quite different then.

The quote by Robert Harris reflects on how social mores—the accepted behaviors and norms within society—evolve over time. He points out that what might seem normal or accepted today, such as two men holding hands in the streets, would have been considered astonishing or shocking in the mid-1970s. This highlights how societal attitudes toward issues like sexuality and relationships have changed significantly over the decades.

Harris also touches on how attitudes toward casual relationships or having a fling with someone were different in the past. This suggests that people's views on intimacy, relationships, and public displays of affection have shifted alongside broader cultural changes. The quote illustrates how evolving social values influence what is considered acceptable behavior.

Originating from Robert Harris, a British author and commentator, the quote offers a thoughtful observation on cultural transformation. His perspective sheds light on the fluid nature of social norms and encourages reflection on how current attitudes might also change in the future.

In summary, the quote emphasizes that social attitudes are not fixed but continually adapt with time. Harris reminds us that what once seemed taboo or unusual can become widely accepted, illustrating the dynamic nature of society and culture.
