The Screaming woman

There is this woman who lives in a flat who's window faces into an interior patio out onto which our bathroom window looks out into. Here in Barcelona the old buildings have lots of these secret patios which are I think designed to let light into the dark recesses of some areas of the building. You can't acess them but they are just there... Not all of them work... The tiny interior patio which the spare room, dressing room and salon all have windows to, brings in a tiny ray of sunlight for approx 10 mins every day. The rest of the time it's DARK and grey and serves no visual interest whatsoever... Anyway, back to the bathroom interior patio. Every day at around 11am there is a woman who screams out her window into this interior patio. It's very regular and it's rather upsetting. I've never seen her, I only hear this agonising scream... Every day like clock work. Ollie says it's a common thing in Russian villages... Old people suffer from it and it has something to do with isolation. I'm not too sure if that is the case here as we're right smack dab in the middle of bcn... there are hundreds of people around all the time and although you can still feel isolated when in a huge mass of people... well you get the idea... I sometimes worry that she's locked in... or being tortured or other times just think perhaps she's mentally ill and can't help it... either way it's pretty unsettling... especially for unsuspecting house guests! I don't know how to ask my other neighbors about it... maybe they know the secret...
