Franz Kafka, one of the greatest writer of all time. Writer of book "metamorphosis", a short but very significant work, which can be read in day if not hours.
Story ; Gregor samsa, a traveling salesman, one day wakes up and found himself transformed into insect (i,e cockroach) with human mind and understanding. It is genuine bewilderment, that what happened to Gregor. The one who reads starting pages will initially expects, a miracle in the end of story but it is not so. Initially Gregor, thinks it's transformation to bug is mere a dream, but later his body feel pain and burden, realises his transformation is a reality. His family ( Mr. And Mrs. Samsa and Grete, his sister) understand that they have lost the breadearner. His sister is now, left to take care of him, who provides him with food. One day Grete and mother, were taking furniture out, Gregor frightened his mother to which he was not intended. His father is turned against him, for he did to Mrs. Samsa. The family has, turned fully against him, even his sister. They want to get rid of him as soon as possible. Gregor, Listened her sister's words, she said " it's got to go" You've to get rid of Gregor. How can that be Gregor ? If it is Gregor, he would have seen long ago that it's not possible for human beings to live with an animal like that and he would have fine of his own free will. Next day , when cleaning lady, shouts the the bug is dead, whole family starts cheering for what they intended to get rid of, became true. After the lady tells them, the whole happenings, she had witnessed, while cleaning the Gregor's room, whole family starts mourning. The family settled in another apartment afterwards, hoping, Grete will be their future.
In my view , the story stresses upon changes in Human emotions, sentiments and relationships.
Gregor, the only breadearner and care taker of family, when transformed into insect, it was his only sister who's emotions, sentiments and relationship reamain true, who provided him with food. Even his father changed his behaviour and mend his way after this process.
Above instances, makes it clear and avid at huge content that, the change is a human nature, one can't blame anyone for the transformation.
