I know that there was the telephone but a few minutes call on a telephone would still leave people feeling lonely.
Phone calls had a different perspective about them back then....or they certainly did where I lived.
Because it didn't happen every day (unlike social media) villagers made more of an event out of making or receiving phone calls from friends and family. It was a talking point for some time afterwards with your neighbours, with almost everyone in the village sharing their news from those phone calls.....whether it was good or bad news.
In turn, that information would be passed up and down the lochside between friends in different villages.
As an example - I remember when the McLeod's son Norman took a years secondment from the Forestry Commission to the Canadian equivalent, everyone on the lochside would regularly get updates on how he was doing. I learned about time zones from when he used to phone, as he'd phone in the morning at weekends but it was afternoon in Britain.
Everyone asked after him and if you passing our village then you might pop in to the McLeod's for a cup of tea and a biscuit to hear how he was doing.
