Wrong Number
Try as I might (alright, I didn’t try that hard), but I can’t find an explanation for this story. The only explanation I could come up with is telepathy. I know, I know, it sounds crazy, and telepathy probably isn’t real. But what other explanation is there? She says she didn’t know her friend was away at a schoolmate’s house.

Maybe through some sort of telepathy, she sensed that her friend wasn’t home, and she somehow knew which number to call. Maybe they’re such close friends that they developed this telepathy connection. If this story is real, I’m not surprised it still boggles her mind to this day. I would feel the same way if something like that happened to me.
