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

If you answered this 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 arrested serial killers took part in the test and answered the question correctly. If you didn't answer the question correctly, good for you.

Be sure to share the test! Also, if you answered correctly, please let me know so I can report to the police. haha!
