BBbevan - sounds the sort of community I would embrace. I am, and always have been. more than happy for anyone to ring the bell and always invited in. After all, I assume they are visiting ME, not doing a check on the standards of my housekeeping.
When I lived in a small Close, and had retired, I was delighted to be able to take in parcels for people at work, etc. They were always very appreciative and would respect my age and only call for their parcels at reasonable times. It was good to feel of use to that small community.
In my block of flats, anything being delivered like that is able to be left in the our large entrance foyer, and anyone around there when a deliverer is trying to leave something will open the security door for them to bring that in, provided the name on the package is actually someone who lives in our flats.
Unlike Mrs Thatcher, I am a great believer in 'Society'!!!
