There's something strange about the travel bug: no known cause, predisposition or cure but you know when you have the tell-tale symptoms of wanderlust and itchy feet. I know I am definitely a sufferer and it lead me to be incredibly jealous of Stu & Fi's round the world adventure. So much so that by christmas I had resolved to gatecrash at some juncture and I was fortunate that their plans took them through the endlessly diverting country of Vietnam.
