This is my picture with the Berlin wall so typical, some of you might think. I chose to put this picture, not for the touristic side of it. This wall that attracts so many tourists around the world nowadays had a completely different presence just twenty years ago. This doesn’t mean that the wall has completely disappeared. We can still see some of its pieces here and there in the city. However, in people’s minds, it no longer has the same power - its meaning has changed. Humanity has the power to decide to change the meaning of all the walls that are dividing its people, if it realizes that no matter how powerful can be their presence, they are all fictitious, after all. For that, it needs good will and cooperation. This is how, a Moroccan girl like me ended up in such a multicultural, multinational and multicolor master class, where people from different parts of the world came to learn how to cooperate with each other, and how to help their countries to do so in the future. If I think that the world has followed the wrong path to reach co-existence and social justice, I also believe that the launching of such programs can help some people to realize that there simply might be other alternative paths. To add some (boring) information about my little person: my name is Aïcha Dellero, I am 23 years old, and I graduated last year in International Relations, with a concentration in Cooperation and Development in the Middle Eastern and North African region, and a minor in Business Administration in Al Akhawayn University in Ifrane, Morocco.
