Different. But that is an understatement (also Indonesia is only one of many countries in the exchange program).
Learning a new language, culture, customs, and getting used to food, not to mention common habits... All part of the experience. We lived in a village of 300. No toilet paper, food is spicier than hell, and the heat is bakin'.
But, and this is a big but, you still have your group. This kind of experience really tests your own wit, will and everything else. Yet it was one of the most amazing experiences in my life.
After the first two weeks of arrival, I got sick (not sure wholey why), needless to say, part of it I believe became psychological (due to the food), and I couldn't eat normally. Surprisingly, it was pizza that grounded me and I was able to eat normal again (this is a long story short).
But during my time there, it was food, the hardest thing to get used to. Not the fact that we'd use our left hand to wipe our butt (oh you better believe it! That's why it is looked down upon to use your left hand for things like taking something from someone, or indeed touching them). Plus they don't have normal toilets like us. The language itself was relatively easy (there are no tenses, conjugations and conjunctions). And you also get used to mannerisms, like shaking hands (which is different somewhat from here) and even as simple as passing in front of people who are having a conversation.
While this does sound very adverse and all, they do give you an orientation on all such matters, plus there are people in charge that you can talk to. But most of all, your group is like your lightning rod, specifically your counterpart buddy.
I'd seriously suggest it to anyone who would be considering travelling, or indeed experiencing the outside world.
Of course, other continents are also part of CWY, so during your orientation, you can choose your preferred region.
Oh yeah, forgot to mention, we were there when the Tsunami hit, but thankfully we were 500km inland, so we were not affected.
I've also traveled 9 months in Australia by myself, so I can definitely give thanks to that program on ways and means of pretty much survival. Though of course Australia is not as different as Canada.
There are 4 steps of culture acceptance/shock they emulate the cycle of a human. First it is like the child stage, where you accept the country, and are really excited to go there and all happy, and uncaring. Then there is the teenage stage where you are rebellious, question their culture, and otherwise don't accept it. Then there is the adult stage of accepting some things then there is the older stage, where you just accept the fact that you are in a different country and respect the differences. One can always jump from any of the four stages, it never stays in any order.
Also if I am making little sense now, that is probably because it is now 6am, and I haven't gone to bed yet XD
