Last weekend I was camping in a Michigan State Park which has fairly secluded sites, (Pontiac Lake State Park), and mine was one - I could only really see the two neighbors across the road so I was happy.
There was a three pair group of nice folks in their late twenties across the road and we'd chatted and introduced dogs to each other. They were quiet and nice but on Monday morning at 0230 I'm woken by just loud enough drunken chit chat to wake me. That level of chit chat is impossible to get back to sleep to and about 45 minutes later they started imitating electric guitars...
I opened the trailer door and in my best ex-military SNCO voice I simply yelled "Gentlemen, Quiet Please!"
Silence came immediately and in the morning I quietly packed up and left before all but one girl who's dog needed a pee woke up...
Not everyone who act senselessly are senseless - sometimes they are just unaware they are causing a problem. Had we both been there another day or more I'm sure we'd have shared a beverage or two and apologies from both sides would have been exchanged.
