Dad -
You forgot the most important aspect of the buildings. They are completely unadorned and unremarkable except for two aspects: they're really big and there are two of them. That's the punchline. The real kicker is that you're looking up at this massive tower that seems to have grown full-formed out of the stuff of the city itself and you marvel with the innocence of a 12yr old about how amazing it is that man could have created something of this scale and wonder at the impossibility of the existence of this object and the tower replies, 'you know what? there's another one just like me over there.'
