I got this in an e-mail years ago, it's supposedly a test that was given to many suspected serial killers, over half of them got it right. I'm no serial killer, but I got it right, no one else in my family and only one co-worker of mine got it right.
This is a genuine psychological test. It is a story about a girl. While at the funeral of her own mother, she saw this guy whom she did not know. She thought this guy was amazing, so much her dream guy she believed him to be, that she fell in love with him there and then. She unfortunately failed to get his name thus after the funeral had no way to find out who he was or how to get in touch with him. A few days later, the girl killed her own sister.
Question: What is her motive in killing her sister?
I'll give the answer tomorrow, If you know it because you have seen it before, or looked it up on the interent, please hold off on posting, lets see who can get it.
