On my exchange I created together with Franka a living room in the hallway of the school of furniture we found on the streets. We did this because there was no meeting place in the school where you could just sit and meet people who you would otherwise never meet. Although the living room was discussed before and allowed by de direction of the school, they didn't like it when we actually started it.
They took our furniture away without letting us know. We put furniture back and they took it again. This happened over and over, for about four months. We wanted to push the direction to tell us that they didn't like what we did, instead of just taking our furniture. We heard this happens quit often with artworks of students which don't fit in the vision of the school. Because we were exchange students we didn't have to be afraid of the board, so we used our position and challenged them.
