You know what's really starting to scare me, for the last two weeks on a saturday night, three of us in my flat have heard a girl crying in the courtyard, yet there has been noone there.
We happened to mention it to one another when we were in the kitchen, and we got all scared, then jumped because someone knocked at the door (there was no-one there either which freaked us out even more!).
So 4/7 of us has gone home for the weekend, i am going to be listening out on saturday night!
