My intercom has just rung. Naturally i shall not answer it. Anybody who knows me, should know by now that I do not answer it - unless I know that somebody that I trust is coming round upon a particular day and time. They also know that in this block - various people with 'police records' try to talk their way in - via that intercom system and so one doesn't answer it - so as not to be pestered by such people. Various other residents in this block who answer their telecom have been horribly pestered by such people...ringing their intercom day and night.

If you do not answer it - they think that nobody is 'resident' in the flat and then tend to ring other flat residents - those who are known to answer their call...
