The Answer!

In answering the question, most people I know (myself inclusive) had it wrong.
That's not necessarily such a bad thing. Matter of fact, it's a good thing.
Why?

Answer: She was hoping the guy would appear at the funeral again.

If you answered correctly, you think like a psychopath. This was a test by a famous American psychologist used to test if one has the same mentality as a killer. Many serial killers took part in the test and answered the question correctly.

If you didn't answer the question correctly, good for you, neither did I.

If you got the answer correct, kindly let me know and I'll take it from there.

The Question!

Someone sent this question to me a while back.
I pride myself on being smart, but I actually answered wrong (wonder why since it seemed pretty simple and rather straightforward). I felt almost better when just about everyone I asked got it wrong too, and these are smart people (at least they pride themselves on being smart).
Want to share it (see how many actual smart people are here). Here goes:

A woman, while at the funeral of her own mother, met a guy whom she did not know. She thought this guy was amazing. She believed him to be her dream guy 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 is her motive for killing her sister?

If you've already seen this, you know why you shouldn't get it right!
