When I was first married our house was open to callers 24/7. So long as they didn't mind the clutter and mess we usually lived in with 3 kids and 2 dogs, they were welcome. I liked it that way in stark contrast to my mother's way of hiding from casual visitors or expecting at least 2 weeks notice of a visit! She thought our friends calling on us when they were passing was dreadful.
But fast forward 20 years to when I turned a hobby into a business working from home, and it began to irritate me that visitors (however friendly we were) expected me to stop working and sit and talk to them. To them it was still my 'hobby', never mind that I had jobs to complete and deadlines to meet. I usually just carried on working as they watched and talked. Sometimes they just got bored (or felt in the way) and left. I began to ignore the phone and not answer the door.
Now that I'm retired and my time is entirely my own I just ignore casual callers and the phone if I can't be bothered with them. Perhaps I'm turning into my mother, heaven forbid! We rarely see our neighbours, perhaps 2 or 3 times a year! We have acquaintances locally but don't know them well enough for them to call on us. Our longstanding friends and our children live too far away to just drop in. I think the lockdowns also showed us that we actually prefer, and are content with, our own company and a degree of isolation.
We only ever had one caller who refused to leave - an insulation salesman whose 1 hour appointment turned into four! We had listened to all his patter and demonstrations, but after several cups of tea and numerous strong hints I asked if he would be staying for dinner and had he brought his pyjamas? He then got very stroppy and accused us of wasting his time. DH let the dogs in from the garden (it was raining and they weren't happy) and he left in a hurry.
