Martin,paranoid or not,she is a single lady and i think someone has noticed and they will take advantage of the situation,it's in her interest to keep surveillance and record activities outside her flat,
lately there are too many tragic circumstances going on,she would be wise to step up her security
and monitor events,as she says the Bizzy ARE TOO BUSY To attend,they only attend when it's too late,
like you say it could be their way of sussing out what she does about it,if she ignores those bricks,they'll
think she just think it's kid's messing about,
