It's been almost two years since his first attempt–this is going to happen today. He jumps out on his desk, opens the roof window enough to get him out, disarms and tries to pull up. It gets out, but eventually it succeeds – it will get one knee on the red roof tiles, soon the other. He looks at the ground and turns his head slightly.
No, Paul, don't think about it. Careful not to humiliated, he will deny the window frame, and his hands will catch the upper edge of the roof; On the other side is the same gradient as here. He pulls up, his heart pounding like a runaway–what if someone catches him? What if someone fits in his room? What if he falls? What if one of the neighbors sees him and thinks he's an experienced thief?
