Non-threatening. Some people expressed concern over us traveling in an area where pirates were known to operate, even though it has been generations since this has been a real problem. The mostly-Muslim population has likely caused some to silently wonder if westerners are treated well and/or welcomed. It is safe to say that we have NEVER experienced more welcoming situations - being invited into people’s homes, schools and their lives. Coming from a privileged society, we are taught to be wary of those who want to take what we have. Other than the occasional overzealous salesperson or bored fisherman, everyone just seemed interested in our differences and wanting nothing more than to share our time.
Isolated. I can’t imagine how hard it is to get people, supplies, physical goods from one end of the country to the other. The majority of the islands are volcanic and very, very rugged. Some places only had electricity for a few hours a night. Supplies might have to be brought by private boat for the entire village from another island seven or eight hours away.
Under-Educated. Indonesia only mandates six years of free education for all children. School after that is not mandatory and is out of reach financially for most citizens. This doesn't mean that the under-educated have no future - it is just limited to staying likely within their area, almost certainly within their country and having a limited access to other religions and ways of life. We met and spoke with some exceptions - they spoke English. The majority will live subsistence lives and have to be OK with that. Most are.
I'm very glad we are getting such a wide view of this interesting country that I really hadn't given much thought to, prior to our trip.
