A or D I think, but I really think it's A.
The speaker thing that he is going to die soon because he spent his life for the purpose of pleasure without paying attention to their well being.
you can see it on these lines :
- We left school
- We thin Gin
- we die soon
hope this helps
More info needs to be provided……
I think it is C. "The neighbor.", because the narrator doesn't give a name, and is talking about someone else.
