The Randomness of Kafka

All of the sudden after K. is accompanied by the Usher he finds himself not being able to breathe properly in the midst of the mustiness and damp air found in the dreadful law offices. I literally have no idea why this would be in the book.. Many things he writes I feel like there will be a reason for putting them in, but this part just seems like a waste of space. Maybe we'll find out later.

Also.. I'm wondering if this [the title that I made for this post] could be a possible topic for the paper we're writing later on. Does anybody have any feedback or suggestions about this? Maybe there is not a sufficient amount of information from the book to support the idea, idk. Someone help!
