On Living in the Netherlands Part 1

I am starting a list of things I find curious about the Netherlands.
1) Trains
Ok, tonight in the train there was a guy playing a guitar and half of the train car was either singing with him or chearing. People here are so friendly and open that it is hard to believe sometimes.
2) Weather
I know that it rains a lot but because of the rain you get to appreciate every second of sunshine more.
3) Football Games
At the start of the game the players throw flowers at the public. How Dutch is that?
