This seems to be almost living in my inbox recently:

This is a genuine psychological test. It is a story about a girl.

While at the funeral of her own mother, she met a 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… A few days later, the girl killed her own sister.

Question: What is her motive in killing her sister?

If this actually worked, then I would be some kind of raging psychopath, given that I didn’t just get the ‘psychopath’ answer, I got it instantly. It was perfectly obivous to me. I’d love to sit and debunk it myself, but Snopes does a much better job than I would.

And if you’re interested, the answer’s there too.
