I've been racking my brain over this... I knew the first word was Gai, but had to look up the second. I don't think it was Lao. The more I think about it, my mom used the word Gai Chi, or Gai Zhi. Apparently, the latter means "calcium", but she was adamant that it was an epithet used of white missionaries who did a lot of harm to the peasants. I can remember her using that word when visiting friends. "Bu gai chi!" meant "No white devil". We all knew what she meant. Sometimes she would call me "Mr Gai Chi", and I knew I was in for a talking to later.
I always deserved it, too.
I love to travel, and I've missed two ScubaBoard trips already.
One of the principles my mother really instilled into me, was to always know that you're the guest when not at home. Never intrude. Never take advantage. Never oppress. Bu gai chi! If it's their home, then it's their rules, even when you pay to be there. Learn some customs, even a bit of their language, if possible. You'll get some diving in and maybe make a few more lifelong friends at the same time.
FWIW, there are two main dialects of Chinese and a bajillion variations of the two. My mom spoke both Mandarin and Cantonese from her birth. I have no idea which this belongs to and my mums not around to clue me in. Apparently, neither of my sisters remembered a whole lot of Chinese, but rather the French that was my mom's family's language.
My mom was amazing. Born in Tiensin, she went through WWII in a Japanese run "European Concentration Camp". My dad the Marine Pilot, helped to liberate their camp and the two were married soon after. I remember 10 days, while my sister thought it a few months. Who knows who is right? They got married. My eldest sister was born in China, and I was born in Barranguilla Colombia, where my dad flew helicopter for Standard Oil. My grandmum was English, my Grandfather a Nederlander, and neither spoke each other's native language, so they settled on French. I bring that up, so you can understand why I love languages and cultures so much. I simply can't wait to visit all the Nederlanders in Bonaire during the upcoming ScubaBoard Invasion. I aim on being there.
