I've just realised this is probably very odd. We live in a town where we know people (colleagues, DC parents, neighbours) but none of them well enough that they'd come to our house (announced or otherwise). DC have their friends over frequently but we get almost no adult visitors.
When we see our actual friends we always arrange a meal or night out or a trip/activity somewhere. They all live around an hours drive away so we tend to meet half way. Our parents do visit but it's too far to come unannounced so we all know they're coming and most of the time we make the drive to them as they're getting older now.
No siblings, lots of extended family but none of them bother with us (gave up trying to maintain relationships a long time ago).
I dont know if this is abit sad. As an introvert I kind of love it! I can fully relax in my own home knowing the doors never going to go. Anyone else in a similar situation?
