In my mid twenties I took a break between jobs to spend a month with friends of my family who were living in Zimbabwe. During my stay I set out on my own for Victoria Falls. After a couple of days there, and an overnight trip on the Zambezi, I'd got to know a few international backpackers. But I was still very surprised to hear someone calling my name on the main street in Vic Falls. So much so, I chose to ignore the woman's voice. When I'd heard my name called several times I turned to see a really good friend, whom I'd known from Infants School to Sixth Form.
