Answer:
The narrator is the younger sister of Aloo and the youngest daughter of Mother.
We can know she is the narrator through her use of "I", "Me" etc to refer to herself while using third person to refer to her brother and other characters.
Step-by-step explanation:
The story "Leaving" by M G Vassanji revolves around a young man's want of going abroad to further his studies while his mother thinks it's unsafe. Though narrated from a different person's perspective, the story seems to revolve much around the mother-child relationship.
The narrator of the story is the young daughter, the youngest daughter of Mother, and the younger sister of the young man named Aloo. The story is narrated from her point of view, using the first-person narrative voice.
We can know she is the narrator because of the use of the pronouns such as "I", "me" etc all indicative of the narrator while she uses third-person pronouns to indicate her brother and mother. The story also begins with the sentence "There used to be five of us and Mother, but now it's just Mother, me and Aloo".
