The exchange took place in tortona (Piedmont, Italy) from september 5th to September 13th and involved Tortona (Italy), Birgu (Malta), Dublin (ireland) and Kerava (Finland): 37 young people aged between 14 and 17 and 9 youth workers faced the concept of European citizenship through goals referring to the "magical" number 20. We are convinced that the earlier we start to work on the idea of "being European" the better the result will be.Being European has to become like a second skin, Europe needs to have a unique and special value and meaning, a Union that determines something more than the bare Union of countries and peoples.That's why we decided to play with the number 20:What will be of us in 20 years? How will be to be 20 in 2020? Which europe will we find in the future and which Europe will we contribute to build?The topic was developed through creative challenges, games, shared responsibilities, team work, group discussions and workshops, visibility actions, etc: for example a big mosaic was built in the main square of tortona, 20x20 portraits of the young participants in 20 years were drawn and used to decorate the youth centre, dream catchers to reflect on our dreams and hopes for the future Europe were created, a thematic path of "2020 steps towards Europe" was initiated and a flash mob ("explosion run") to involve citizens in a European colors explosion (as to symbolize the peaceful coexistence of different peoples and cultures in Europe) took place. 2020 was our magic number:E - to Enter in a group of 2x20 people and to build a different future togetherU - to Unite our efforts for a common objective and path: the Europe we want to live in (in 2020)R - to reflect together on rights, challenges and opportunities that Europe can offerO - to Obtain results by working together in a common effortP - to Participate, to talk, to listen...to discover together the different stories of EuropeE - to Experience a European feeling, get to a common sense of what Europe is and what values it promotesAt the end of the exchange we worked on 20 ideas and tasks in order to foster European identity in our own lives and in our daily relationships and habits...to walk together towards Europe 2020.
