Cultural differences

Yesterday I had class and we were discussing the bad behaviours and the "ugly" topics that we have in our country compare with the ones they have here, in Finland. It was funny because I said that in Spain you can talk about every topic you want, you are in public transport and you can listen to conversations about politics, religion, clothes, sexuality, weather, trips, etc. obviously depends on the person but you can talk mostly about everything; and people from other countries were really surprised by that,  for example, in Finland is not polite to talk about money, it´s an annoying topic for them. And I think that in Spain we are more open-minded than here.
It´s funny to find so many differences between countries, also they said in the class that it´s really unpolite if you speak loud on the bus, and in Spain, everyone is talking quite loud. One girl also told me that when she went to Tenerife, she was waiting for the bus and the people who were waiting also were really close to her and she didn´t feel comfortable with it, because here people keep the distance.
Here, in Erasmus, you really discover all the differences we have between nationalities and the strength of the culture. It´s really good to open your eyes and realize that not everyone is like you, not everyone likes the things you like, not everyone has your customs or understand your jokes. It´s an opportunity which gives you a lot of culture and knowledge about life and countries and makes you very rich.
