The Murderous Sister

[Sidoh]

A woman attends her mothers funeral.

At the funeral, she meets a man.  She chats with the man and gets to know him a bit better.  After only a few hours of talking, the woman is convinced that she has found her soul-mate.  She cannot believe how perfect the man is for her.  However, she has to leave in haste because she gets a phone call.  She forgets to retrieve the name or contact information of the man.  She spends weeks trying to find him, but to no avail.

Three weeks later, the woman murders her sister.  Why?

[Ergot]

The logical answer I can get from this is that the woman had recieved a call from her sister and blames her for losing the perfect man. Of course, this is not right answer... It's too simple, and you're trying to decieve us

That's incorrect; I'm not trying to trick you, either.

There are some pretty interesting facts about this riddle, I'll tell them after it's solved.

Ah yes, that's it. 

That's another one of those things that I suspect is an urban myth, though, just like the one about kintergardeners getting the "dementia" one.  But who knows?
