Cambodia is hot. And it's muggy. I wore jeans one day and almost died (well ... not really, but I was uncomfortably warm).
And so it shocks me to see locals wearing thick jumpers and even gloves in 30C weather. It shocks me even more to see them wearing socks with thongs (flip-flops). Worse still, they actually sell socks with a separate big toe so they can be worn more comfortably with thongs. Really? Really??
