We met Robyn, an Australian teacher at the Khartoum International School, at the Blue Nile Sailing Club. She was so kind to us whilst we were in Khartoum and invited us to a dinner party then even to stay for a couple of nights. It was wonderful to have a bed, hot shower and the use of her internet connection. We're looking forward to her coming to London one day so we can repay the huge favour.
