People still have landlines?
We have one according to BT, but we’ve never plugged a phone into it.
My parents in their 70’s despite both having mobile phones still treat it as a gospel, if it rings, they do all they can to answer it then get annoyed that it’s a cold caller.
Same with their front door, if someone knocks, even if it’s a jehova they still feel an impending need to answer it and say no we’re not interested.
On the contrary, if someone rings me and I dont recognise the number I don’t pick up, if someone knocks at the door and I’m not expecting them it’s likely someone I DGAF about talking to or want to talk to so I don’t open the door, if they knock twice I ask what they want on the ring doorbell as it’s usually almost always something to do with charity or cleaning my gutters. They can’t wrap their head around this and usually always say “but what if it’s something important?”
