Travelling the world is a glorious adventure, and one where you will meet some of the most amazing, decent, crazy and sometimes downright mental people on the planet. You can meet some amazing friends on your gap year, but you can grow distant from some old ones too, and even the new ones you meet can be in your life for years, a week or so or just one night. Playing the game of social roulette and constant hellos and goodbyes can sometimes be hard, and as a long term traveller you do have to be prepared for that.
