It surely brings another perspective on the way that you look at your surroundings. Whilst during the cold, dark and grey winter months people in Stockholm are seen as cold and introverted and unhappy. They're always stressed to and from work. They look unhappy and depressed, grey as the weather.
When spring comes around the whole city lights up and the world is seen through a rainbow. People stop stressing and there is suddenly no hurry to work or to get home after. The days are longer and parks and terrasses are filled with face turned towards the sun, soaking up as much vitamin D as possible.
I love this city! It is the most beautiful one I know. I just wish that the summer months were longer than the winter months.
