Come over for a coffee

When I was a child, my mum met her friends at their houses, for a coffee. Or they went for a walk, through the woods, along a river to a beach.

Now I’m the one who meets my friends for a coffee, a walk, or maybe a run.

When I was a kid, this made no sense to me at all. Why would you want to just go sit somewhere with somebody? The question was what were we going to PLAY.

What was the storyline, the process of change that played out between these two points? Was it gradual, or did it happen all of a sudden?
