If you have a set of blocks, mechanical, physical blocks,and I tell you to build something and I say, oh, by the way, you have to cut the blocks in smaller pieces, you are going to get angry, aren't you?
The houses, which were purchased by the city and must be moved away from the flood-prone Red River of the North or a creek that flows into it, are so large they can't be hauled to higher ground without being cut into pieces.
