As my dear friend says, don't sweat the small stuff. Also, when something goes wrong travelling it's often an opportunity - for me, meeting Mr GPS was something I'll never forget. He has obviously helped people before and knows exactly what to say and how to say it. What a privilege to meet someone like that! And it would have never happened if we'd magically figured out all by ourselves that you go up two unmarked escalators. Where's the fun in everything going right? ;-)
