Another idyllic day in Korea (twist ending)

Here's a brief description of one of my recent weekend days

After a lazy start to the morning I decided to take a bike ride out to the green tea farm cultivated by my buddy the monk. It's about a 90 minute ride along the scenic river then steeply up into the mountains. The day turned into a bit of a scorcher ~90 degrees, so I was happy to stop at a villiage on the way back to sip some sweet iced rice based drink out of a dried gourd in the shade of a traditional open air market.
Back home I visited my friend who works in a sandwhich shop. Since it was so hot I asked him about swimming in the river. "I don't know, it's pretty dangerous. Every year people die."
"Really?"
"Yes, this summer a middle school student drowned."
Of course, this only strengthened my resolve.
So around 6 o'clock I head down to the river bank. We have a peaceful pine forest park, and some tennis courts a little further down the bike trial that runs along the river, and the river itself has a wide sandy bank; it would make for a nice beach if it was on the ocean.
But before I can take a dip I'm sidetracked by a group of Koreans (strangers) at a picnic table calling me over. For them it is exciting to talk to a foreigner, and for me it is fun to have a conversation almost entirely in Korean. Of course the conversation wasn't too deep, a bunch of random nonsense, but I suppose the same could be said for most conversations between 1st language users. Another similarity between this conversation and a generic one between strangers is that it was fueled by booze and thus plenty entertaining. I can't tell if it was some kind of soju cocktail, or maybe a fermented fruit juice, but it was sweet and strong whatever it was we were drinking.
Anyway, after an hour or two the party broke up, and although it was dark by now it was still hot and I was still looking forward to that swim. The water was glorious, it was shallow, calm, and just the right temperature. I really felt peaceful seeing the mountains surrounding my town lit up by the moonlight and reflected in the smooth ripples of the water in which I swam; the quiet stillness broken only by the occasional splash of a jumping fish, or murmer of conversation from the park on the banks. At length, I emerged and walked up stream to retrieve my bag.
I found it surrounded by policemen! Apparently it is against the rules to swim at night. If this was Orange County California I would now be facing handcuffs and a $100+ fine, but with the good men of Hadong police force it was a simple, "We thought you were dead. Please don't swim at night." And I head home for a well earned night's rest.
