Agree with everything you say except the final point - I absolutely LOVED being out clubbing until 3 (4, 5…)
Maybe it was just a product of my time as a young person, but being out that late and having a great time long after most people were asleep just felt so fundamental to my young adulthood.
That’s not a criticism of those who prefer to stop sooner though, just a statement of how doing so would have felt alien to me. Each to their own though, as always.
