If I follow this map, it should be the observation room, but I arrived at the cafeteria earlier. I am rechecking the guide map inside the permitted school area. Could you maybe read just one section with me? Instead of difficult navigation calculations, I want to find marks that even first-time visitors can recognize. Like windows or floor colors. May I show you my notes first? If you're busy, I'll ask the information desk. This time, I'm trying to start by admitting that I don't know.
