How's the serenity!

When I moved in the weekend before last, the first few nights it was really difficult to get much sleep.To much background noise, particularly the fan just outside my window. And I'd get woken by the street cleaners at far too early o'clock in the morning.
After a couple of nights I got some earplugs, then I slept fine.
The last few nights I've been able to sleep fine without the earplugs, because I've gotten used to the noise.

But tonight I was planning to go to sleep early due to tiredness, due to it having been so hot today. But there's been so many people in town, making heaps of noise, because tomorrow's Australia(n Invasion) Day, so they won't have to go to work. So I haven't been able to sleep.
So I ended up going down to the Flinders Street steps to see if anyone I knew was around. There was one guy I know from Credo, sitting on the steps with two other guys I didn't recognise, so I hung around with them for a while.
So these two policemen came up to us and asked the younger one of the guys that I hadn't met before if he had any ID, because there was a Smirnoff bottle sitting next to him, and they didn't believe that he was eighteen. He gave him a Health Care Card, and they asked him what his name was, and his date of birth. He told them his name, but said he didn't know what his date of birth was. Because he wouldn't tell them his birthdate they said they'd have to arrest him for sitting on the steps (apparently against the Transport Act), although the two other guys were also sitting on the steps, and there were about a dozen other people sitting on the steps. He still wouldn't tell them, so they arrested him.
He came back about ten minutes later and told us that he'd given them his brother's Health Care Card because he was sacred of them, and thought he'd have to go to court for underage drinking. The cops came back again and the older guy that I didn't know told them the kid had given them his brother's card because he was scared. So the cops got the kid to come back into the station. They said he probably would be let off though.
I realise they probably just want to scare kids out of breaking the law, but if they hadn't tried to intimidate him he probably would've been more likely to tell the truth, although it probably still wouldn't have been likely. I don't know if what they did would just make him resent police officers and be less likely to trust them.
