“First they came for the communist,
and I didn't speak out because I wasn't a communist.
Then they came for the trade unionist,
and I didn't speak out because I wasn't a trade unionist.
Then they came for the Jews,
and I didn't speak out because I wasn't a Jew.
Then they came for me
and there was no one left to speak out for me.”

I remember the first time I read this quotation of Martin Niemöller. I was 12 years old. I could not understand why I was not allowed to go to the park, with my older brother, in the evening. That park in Buenos Aires was the place of reunion for a neonazi group, and my brother was too mentally ill (he had dementia) and not enough white skinned to stay there. Imagine my surprise when my mother told me that this kind of thing happens every day all over the world. To lift the veil of disillusion from my eyes, she made me read this Niemöller's poem, telling me that the future was in my hands. This changed my life. Since that day, I tried to do my best to change the world, not the whole world, but at least small everyday things, misunderstandings, discrimination. I joined different charity groups and I also went every month to the poorest neighbourhoods of my city (the so-called "villas miseria", like the Brazilian "favelas"). When I was 16 years old my older brother died in tragic circumstances never fully explained, and we could not even prosecuted the responsible. It was the moment I decided I must be a lawyer.

During the high school, I was chosen, with other eight mates, to represent my country in the USA during a course of leadership and international law. I also won a research competition sponsored by the Canadian Embassy and I successfully passed the first of three phases of the national maths competition.

When I finished the school, I started my legal studies at Austral University. Even though I always preferred the penal law, I participated in a simulation of corporate law within my university and the University of BuenosAires, that we won. I also was part of an intellectual group about the "Mercosur" where I helped with the investigation and presentation of a conference in Ecuador. Although my german was not extraordinary I decided to do the last semester in Freiburg, Germany, and it was an incredible experience. I did 5 courses, and I participated in another one as a listener because I was not able to do more than five. Last year I successfully achieved my law degree and started an LLM in International Criminal Law at Granada University. At this moment, I am working in my thesis. I am studying the application of the Geneva Convention and their Additional Protocols in the occupied Palestine and the violation of the International Humanitarian Law by the Israelis Government.
Since 2008, I have been working in the NGO "Justicia Ambiental" in Argentina. Last November I also started working as translator freelance at the NGO International Bridges for Justice (Geneva, Switzerland). I also have done some research and analysis of different systems of International and European Criminal Law.

*NOTE*
I have put MATES just in case you mean something else. If you are talking about other students in your year, just replace it with "students". If you literally talking about mates, replacing it with "friends" is more formal.
