The tower really is leaning. So much so that it catches you off guard and you find yourself checking from all angles. I don't think it fits into our small box of what we find comfortable... I mean, the tower is leaning! No building should be leaning. So as much as we enjoy marveling over it, we also enjoying leaving it, so we can get back to our comfort zone of regular, straight buildings that don't look as if they are about to tip over.
