Answer: I think Emily's mother is an unreliable narrator.
Explanation: I do not think that Emily's mother is a reliable narrator because she is speaking in a subjective way. She is a first person narrator who tells a personal story and keeps on questioning herself about the way she brought her daughter up.
I do not say she is unreliable because she is lying. In fact, I think she tells the true about her feelings. However, I believe that the way she narrates the story makes it unreliable, because she gives the reader the opportunity to stop to think and have their own conclusions.
