The Polish journalist Ryszard Kapuscinski, acclaimed as the most brilliant and perceptive reporter of his time, writes in "Travels with Herodotus" that with every new town visited, with every new foreign word learnt, the traveller experiences small, almost imperceptible personal changes. Wherever you go becomes part of you and the person who returns home is never the same as before departing. Knowing new people is in many ways like travelling, and those who you meet along your road become part of your existence too.
