Osama Alomar's very short story "Do Not Forget the Poor" is (in its entirety) as follows, in its English translation by "C. J. Collins with the author":
Even before I arrived at the corner, a few meters from my friend’s house, I smelled a very sad smell. I felt a pain in my stomach, and I found it very strange. When I reached the corner, the sad smell became unbearable. My tears began to fall profusely, leaving me confused. Then I saw a woman in the autumn of her life. Her clothes were torn, like her life. She was covered with the tears of Humanity. I went toward her, shaking from the pain, which increased as I drew nearer. When I was beside her, she looked up at me and said with tears in her voice, “Don’t forget the poor!”
My soul fell into scattered pieces. Humanity looked me right in my eyes, and the contraction of her pupils squeezed my heart. I took a handful of coins from my pocket and gave them to the old woman. Humanity grasped my hand in support. As she took the money, she looked at me with two eyes that gazed into the deepest depths of tragedy. And as soon as the money was in her hand, the sad smell disappeared and the pain in my stomach dissolved. My tears stopped. Humanity patted me on the shoulder and took from the pocket of her white garment a quantity of happiness that would last me for thousands of days, and she planted it in my future. I turned to my friend’s door, but just as I was ringing the doorbell, the old woman let out a volcanic scream that burned the embryo of my happiness, and fell down dead.
Most of this story is clear to me: the woman is a personification of Humanity (not for the first time in Alomar's stories), the "sad smell" denotes poverty (again, not the only time Alomar denoted poverty by a bad smell), and giving money to help poverty brings happiness to the narrator (this could be either the immediate happiness of having done a good deed, or a sort of karma since the happiness is "planted [in the] future"). What I don't understand is the very last sentence: why does the old woman scream and die as soon as the narrator rings the doorbell?
