Okay, I'm going to ask a question, and I'd like each person to answer it for themselves. If possible, answer it for yourself before viewing anyone else's response. Though there is, technically, a right and wrong answer, it is most important that you answer it for yourself. And, if you happen to recognize the question, please don't ruin it for everyone else.
A woman is attending her mother's funeral when she sees the man of her dreams. She is unable to approach him, so the funeral ends without her even being able to talk to him. Two weeks later, the woman kills her sister. Why did she do it?
