Philippa,of course you are right,we all tend to lock our selves away in our so called castles,our society today does not give the security it once did,lack of police on the streets does not help,like the dodo,nearly extinct,most of our neighbors are strangers these days,and the days of leaving the door open have long gone!!!!!!regards John.
