What is Brazil waking up for?

Many of my Brazilian friends which study here in Brunel with me are right now at Parliament square to protest against last days' happenings in Brazil. And when they left, I have to answer the question I've been trying to answer to myself these days: why I'm not going? I don't have a precise answer to that, but I have some things in my mind that doesn't make me feel like going. I believe the point here is the contrary: why are my friends and millions of Brazilians (in Brazil and in the world) going to streets?
