Frankly - how many phone calls do you really make and take these days?

It's vanishingly rare for me. I got a call from a friend today - but I think I otherwise only make or receive a legit phone call every few days. We use social media mostly. Work "calls" are on apps.

A family could probably get away with 2 phones easily, as long as they have home internet.

Now... When I was young and internet was over dial-up, having a single phone line for our whole family caused quite a lot of spats.
