(pfft ;3 no window silly)
Robert chuckled as he let the pet try his best to escape, knowing the window in the room was really a fake. He made it seem real by the lighting that was around it and the person who made it did a really great job. The thing looked as realistic as an actual window, though it was just concrete with a bunch of paint and lights around it. Anyone who tried to bust up the 'window' would easily become tired and probably hurt. "Go ahead, tire yourself out."
