I suppose if they were honest every ex-pat living here in Ethiopia will have occasional moments when the only thing they want to do is go straight to the airport and fly home. Well I had my first experience of this two or three weeks ago, in the middle of the night. Insect bites are a fact of life in the tropics, and Chris and I have coped with them intermittently over the time we have been here. I can sometimes be seen sitting at home in the evening with my trousers tucked into my socks as I am convinced unseen bugs are attacking my lower legs from the floor.
