Talk about reverse psychology!
Like Mark Anthony in Julius Caesar, you have us convinced we will learn one thing, but instead we learn the opposite thing lol.
My niece's boyfriend lost his passport, and thought he'd be blackmailed for it's return when someone found it. Instead, the person posted it back to him for free (he was now on the other side of Vietnam) and asked him for nothing. My niece's boyfriend sent him a thank you reward anyway, so I guess kindness can pay.
Sounds like Vietnamese culture is a blast. If you survive it. Remember to always drink plenty of water after a drinking session like that! ;)
Funny that you mention the Romans because I was thinking about their vomitoriums, or puke rooms, that night. I felt much better and kept drinking without a hangover. Never say, just one beer, cause the beer gods will always make it a crazy night. hahaha
