Not quite culture shock, but minor differences...

Here are some things I've observed about Korean life that is new to me as an American:

-To take a hot shower, you must turn on the hot water heater first, then turn it off after. Same goes for the gas to your stove.
-Apparently hoola-hooping is a normal morning exercise for ladies to do outside their apartment.
-NEVER tip your waiter, it's rude.
-Age is very important, so it's totally acceptable to ask people's age, and respect your elders!
-Korean age is different from westerners. When you are born, you are already 1 year old. Once the year is over, you become 2. So if you are born in December, you will be 2 years old a month into your life. So I am 28 years old in Korean age.
-Driving is kind of nuts here. Traffic lights seem to be more of a suggestion, and there are many many intersections without any stop signs, so you just roll through and hope nobody else is also crossing.
-Many people are addressed by their occupation. It's respectful for my students to call me Teacher (they actually call me Roman Teacher), and I call my boss Director.
-There are about 7 or 8 channels on TV that are in English. Unfortunately, most of the shows they play are CSI, Law and Order, and NCIS.  :-/
-When you hand something to someone, or accept something from someone, you should do so with both hands. If you hand something to someone with just one hand, put the other hand on your arm. The higher up your arm you place your hand, the more respect you are offering that person.

Today I went to the hospital to do my required physical check up (blood test, urine test, blood pressure, chest x-ray, vision, hearing, dental). Instead of getting all of that done in one office like in most American clinics, I had to go to a separate office in the hospital for each of those things. They used some equipment that was totally new to me, like when they had me stand on a scale, a flat, metal thing came sliding down from above and knocked me in the head. I was startled and jumped off the scale. Turns out that flat metal thing was just measuring my height. Color me embarrassed!

More to come, I'm sure.
