That question....
The answer is - Because she thought her 'lover' would appear at her sisters funeral.
And, It's a hoax, it was an email hoax, apparently started by an American Psychologist.
It's completely fake.
I know it's a hoax. Everyone seeks simple answers to complex questions, people thought it would be that simple to detect a psychopath. Unfortunately, you can't detect them that easily, so it's a load of cr*p.
I just wanted to see how people would answer...
