خوشحالم که هیچ کدام از شما نتوانستید این چیستان را پاسخ بدهید، چرا؟ پاسخ را بخوانید

It is a story about a girl.  While at the funeral of her own mother, she met this guy whom she did not know.  She thought this guy was amazing, so much the dream guy she was searching for that she fell in love with him right then and there but never asked for his name or number and afterward could not find anyone who knew who he was.  A few days later the girl killed her own sister.

 Question: What is her motive in killing her sister?

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 this test and answered it correctly.  If you didn't answer correctly - good for you.

 HOPE YOU ALL FLUNKED THIS TEST!
