It's going somewhere and leaving a place. It's eating blueberries in the middle of the road and singing songs in sauna. It's a new language and an old friend mixed together, a public transport system you have no clue about, a tram going in the wrong direction which is completely fine and unworrying for you because you've got plenty of time. It's asking someone for the way and hearing a life story instead. It's drinking your milk outdoors and taking your shoes off. It's essential.
