Half asleep on the top bunk in a four-share dorm, I became convinced that I was being harrassed by a mosquito. Having slept every night for the last six weeks under a mosquito net, I was feeling a little exposed - and I'm sure Livingstone mosquitoes carry malaria just as well as those in Katete.
Flailing my arm sleepily about my head, I was unable to get rid of that whiny, buzzing sound - and in my dreamlike state decided that the mosquito must be in my ear.
And that's how I woke up at 3am with my finger in my ear, only to realise that the whiny, buzzing noise was my middle-aged American room-mate's snoring. And even when I was awake, it sounded like a mosquito. Special!
