Look at this as if someone just dumped you off in the middle of the Amazon where you will be meeting a foreign tribe.
This is a complete cultural shift for you. Nothing more. Approach it the same way. This is all VERY REAL ! All of your previous background and understanding(s) do not apply here. There's no need for loads of apprension, only the need to accept you will be learning new customs.
Reacting in a paranoid manner will only raise suspicions, the same as it might in a foreign tribe. And there's no need for it.
Out of time for now.............
It's an adventure. Go into it with a positive attitude and open mind !
