It's just stupid, is what it is. Why kill your sister on the off chance that this guy has a special attachment to your entire family? It seems much more likely to me that he was an old acquaintance of the mother. Makes more sense to have a peek at her yearbooks or something. Don't you think?
That question is fake.
Also, hello guys. :3
This isn't a true story... it is to make you think.
And yes, it may be stupid, but the goal is to illicit an answer, just like a math question, except that perhaps there is no one answer.
Beacuse she wanted to see that man again.
lol i love this question when i first heard it cos i automatically knew it was cos she wanted to see the man again. it applies to 'love' addicts more than anything else. i'm on the opposite end of the spectrum from sociopaths and it was clear to me that killing her sister would be totally justifiable in order to meet him again. lol ;) (for the sarcasm-challenged, that last bit was a joke).
