Julia listened as the twins talked. She had to admit that she had indeed not looked very closely. She had noticed the marble of course, and had commented on the coloring, but it had not crossed her mind on whether it was Italian or not. "You really think they could put another building onto of this one?" She looked up towards the ceiling, trying to picture another building on top of the one they were in. "That would be rather tall."
Looking from one twin back to the next she listened to what they had to say, "I can't really imagine any bigger buildings, but it's quite possible I suppose. So the two of you, when you see a building, you see how it's made more then other things, don't you?"
