Being surrounded by other aid workers does give you a certain sense of camaraderie, but just in case Big Brother left any doubts in your mind as to whether or not people who spend 24 hrs a day together go completely nuts, any aid agency guest house here in Sudan will confirm it.

Even the most reserved and docile colleagues have somehow turned into sexual predators: sex is on everyone's mind, particularly on those eagerly-awaited Thursday nights where home-made Janjaweed Juice quickly rids people of even their final social inhibitions.

Like everyone else, I join the hunt for fresh flesh and eagerly scan each new face – or even a new voice on the phone (!) - for some semblance of sexual chemistry. I rejoice in ecstasy any time I find my stomach doing little flip-flops along the 'yes, you'll do just fine' lines. Of course, half of the time the stomach-churning feeling simply turns out to be indigestion, but it's kind of exciting nonetheless....
