Well Alright Then

Last night my home phone rang. I didn't recognize the name on the caller ID, but since it looked like a real person, not "unavailable," I answered.

Me: Hello?
Voice: Hello?
Me: um, hello?
Voice: Hello?
Me, getting irritated: Can I help you?
Voice: No, you can't help me.

And then she hung up.

I guess it was a wrong number, but how weird is that? She called ME. Couldn't she have just said, "sorry, wrong number!"
