When we agreed to move into our friend's place, I don't think we fully grasped the complexity of what we had gotten ourselves into. I have drawn a diagram demonstrating the complexities involved, to give you an idea of what was involved.

1. First, F has decided to move in with her boyfriend. They both have apartments, so her apartment will become empty
2. Then, Laura will move in with her boyfriend, Igor, into the newly vacated apartment F has moved out of
3. Marie will then move into the apartment Igor has vacated, leaving the aparment in Chatou empty.
4. Finally, we will move into the apartment in Chatou.
