This is a Geniune Test!!
While at a funeral of her own mother, she met this guy whom she did not know. She thought ths guy was amazing, so much her dream guy she believed him to be, that she fell in love with him there and then...A few days later, the girl killed her own sister.
QUESTION: What is her motive for killing her sister?
I will post the answer to the question tomorrow. I want to see what you all come up with!! Then we'll see who's psychotic and who is not!!! 
This should be fun!
