I don't understand at all any fuss about late-night (early morning) noise or loud behaviour in town. I live right in the centre - within a hundred yards of where I live there are eight pubs and two nightclubs and it is very rare that I even notice the noise...
Well there you go. You don't understand because you don't hear the noise. Others do.
I live on the edge of town, a good 20-something minute walk away from the nearest nightclub, and at weekends the screaming and shouting of drunks comes in waves. There are the first batch, returning home after they've fininshed in the pubs, at roughly 11.00 till 12.30. There there's a second batch who've left the clubs early, which lasts between about 1.00 - 2.00, and then there is the final batch, after the clubs shut, which lasts between about 3.00 and 4.00.
A couple of years ago it was so bad that to get anything resembling a decent chunk of unbroken sleep, I had to force myself to stay awake until 4.00am most nights, because it was the only way of getting a guaranteed 4 solid hours of sleep. And after that 4 hours of peace, I had to get up and do a days work....and when I returned home in the evening, I'd flake out for a couple hours until about 9pm. And that went on for an entire summer.
So
you may not have heard any drunken noise, despite your proximity to pubs and clubs, but there are people on this island who
do have to suffer it, sometimes to the extent that it
completely screws their quality of life. ...and for those people, I can personally assure you, the situation is
far from being "some myth".
