Read this question, come up with an answer.
This is not a trick question. It is as it reads. No one I know has gotten it right-including me. this is what the guy who sent it to me said
Unfortunately, I got this correct in about 2 seconds LOL

Lets see how you do?
A woman, while at the funeral of her own mother, met this guy whom she did not know. She thought this guy was amazing, so much her dream guy she believed him to be just 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 is her motive in killing her sister?
