Well the worst thing for me is cold calls be they telephone or on the door.
I suppose to a certain extent you can block cold calls on the telephone with voice recognition and other things you can install. The worst thing you can do is to tell them to fffff float off. That makes them mad and they do it more. I just ignore them I look to see who is calling and if I don't recognise I don't answer,
It is not so simple on the door. Okay you can say sorry you are not interested in double glazing or you do not want any info about various religious sects.
When I was a bus driver for Berlin corporation the BVG Berliner Verkehrs Gesellschaft I sometimes had to do night shifts. I can tell you there is nothing more annoying than coming home and when you are in the arms of Morpheus the door bell rings and bleary eyed you go to the door and two smiling people say ' We bring you good news ' I won't repeat what I told them to do with their 'good news'.
but listen, think about it. Even if you are awake in the day, you could be in the bath, on the lavatory, making your partner giggle in bed. it is annoying.
