While hanging out in my backyard, I found a girl older than me by about a year or two sitting in a stream in my backyard near some children playing in the water. She climbed out of the stream and we started talking. She sees my neighbors house and asks, "You live here?", I reply "No, I live next door". She goes "Huh," and reveals to me a fact so shocking i woke up.
