Answer:
In "Because I could not stop for Death ," the author Emily Dickinson makes use of personification to develop the theme that nobody can escape from death. Thus, in the poem Death is a kind and pleasant suitor and carriage driver: "He kindly stopped for me/and I had put away my labor and my leisure too for his civility/politeness." Besides, the speaker also personifies the sun as "He" and mentions that she is becoming chilly, which suggests that Death leads to cold and darkness.
