The contrast between Tauranga and Phnom Penh in many ways couldn't be more stark. With this shift out of a comfort zone, the comfort of western suburbia which is inherent in the Safe Little World concept was immediately destabilised and then thrown into a light that exaggerated just how obvious our western expectations of comfort are. The sarcastic phrase "first world problems" is probably the most apt way to describe this in a nutshell. But the Safe Little World concept has also always embodied a paradox. The paradox is that our safe worlds have the potential to come under threat - and Cambodia's history and our experience of it as visitors definitely bore that out (encapsulated, for example, in a visit to S-21).
Other than a critique of our western sense of a safe little world in the context of a developing nation, it could be interesting to see if the underlying concept of a safe little world was found wherever we go. The question is, is it a fundamentally human drive, no matter where humans find themselves, to try to create a safe haven? The short answer is yes. This drive may embody itself slightly differently and have unique cultural manifestations, but ultimately this is a very human trait.
No matter how much, or how little, you give a person; no matter the threats, upheavals or fragility, humans seek to create a space for themselves.
