Say what?

I thought my neighbor's were fighting or something. I was hearing a sharp high pitch noise, but it wasn't loud enough to figure out what it was for about ten minutes. It wasn't screaming, it was laughter. Freakishly loud, high pitched, and completely bonkers-happy laughter. I couldn't tell if the person was male or female from it, but I was gearing it loud and clear from between two closed windows, theirs and mine, and all the space in between our houses, like they were right next to me. It was almost like listening to the Undertaker from Kuroshitsuji, and I was like... okay then. Better than having a neighbor who laughs like a chicken I guess. Haven't that girl for awhile.
