We all have friends who passionately stand for a cause. They even leave their rest for later or stop doing things they have to do in order to work for that cause. I have friend like that too! I have a friend Moni: She posts and motivates her friends to try the vegan lifestyle. Another friend, Corinne: She tries to make people get aware and interested in the artistic work of women who paint, write, compose and that have been minimized by history. Another friend, Silvia: She invites people to join protesting marches against corrupt politicians or against social injustices. I can list more friends as well, but unfortunately there are not that many.
