Read this question, come up with an answer . This is not a trick question. It is as it reads.
A woman, while at the funeral of her own mother, met a man who she did not know. She thought he was 'amazing'. She believed him to be her dream partner so much, that she fell in love with him right there, but never asked for his number and could not find him.
A few days later she killed her sister.
Question: What was her motive for killing her sister?
