What are the similarities of vine and johnsy?

Hi your question lacks the short story which is "The last leaf " by O. Henry

the similarities are:

Both Johnsy and the tree were suffering from the harsh weather conditions which made Johnsy sick of pneumonia and made the vine loose its leaves continuously Both Johnsy and the tree were on the verge of death

Explanation:

The last leaf is a short story written by Henry. in this story Henry talks about a Vine tree and Johnsy in the same context. the Vine tree is loosing its leaf which its a symbol of life in a Vine, gradually to the changing of the season to winter, while Johnsy is been sick of a deadly illness known as pneumonia which is also gradually taking his life away from him

The story was short in 1907 in a Greenwich village during a period when there was a breakout in pneumonia due to the harsh weather conditions of winter and how an old artist gave hope of life to a sick woman, by making her clinch her hope on the survival of a vine tree in the open

The similarities between the vine and Johnsy is that they are on the verge of dying and that they are fighting the hardest battle that they could ever have in their lives. Johnsy is fighting pneumonia while the vine is fighting the rage of the storm that may take its life.
