Luca stood in front of his computer desk this morning. He was kind enough to share a desk with Finn, which was why there were two computers on the desk. The one on the left was his, while the one on the right was Finn's.
The space where Finn's computer was now used to be for his books. He loved to read, which was why he had a collection of books, all of which were nonfiction because he didn't like anything imaginative and unreal.
In order to share a desk with Finn, he would need to move the books, and luckily, he managed to find space in the cabinet to put them. That was why Finn's computer was able to take up space on the desk, but Luca actually didn't move two things from the desk even after Finn put his computer there.
