How on earth can it be considered rude to choose not to answer your own front door to an unexpected, uninvited visitor?
Our house is like Clapham Junction, most days. Constant stream of people coming in and out. There are times when I want to literally scream at people "STAY AWAY FROM MY HOUSE - THE DOOR IS NOT GOING TO BE OPENED WITHOUT PRIOR APPOINTMENT"
I don't do it, but boy, oh boy, do I feel like it. Does no-one realise that sometimes, just sometimes, you just want some time to yourself? Why is that difficult to imagine?
I never call in at someone's house without a pre-arranged agreement (emergency notwithstanding).
Years ago, before the advent of any kind of telephone at all, it was normal. Of course. Nowadays, there is absolutely no excuse, whatsoever, for people popping in. We have friends who rock up saying "Oh, we know you don't like popper-inners, but it's only us" - - -
IT IS NOT OKAY TO DO THIS.
My home is my safe place, and I need a safe place to be, sometimes, I really do. I sometimes feel suicidal, and just want to shut myself in my own home, to recharge my batteries, and not open the door, if I don't want to. People turning up on spec does not help . . . at all . . . EVER. It makes things worse, so much worse.
