The Pyscho Test
A woman, while at the funeral of her own mother, meets a guy she did not know. She thought this guy was simply amazing. She fell in love with him right there but never asked for his number and could not find him.
A few days later, the woman kills her sister.
Why did she kill her sister?
If you thought "because she hoped the guy would show up to her sister's funeral," you think like a pyschopath
