Since my grandson Josh was very young, we've gone on photo walks together. I'd see something I like, take the photo, and then I'd explain to him why I liked it and why it caught my eye. Perhaps it was a reflection in a puddle or a close-up of an object on the street, or the particular way the sun was hitting a building. Then I'd ask him what he saw in the scene, hand him the camera, and get him to "capture his own version." It was our time together. We loved it and we never tired of it.
A great many of my 'grandmother' friends shun social media. They all own computers. They all know how to search for things and they all know how to send an email.
Let me clarify that last statement.
They all know how to send an email but most wouldn't dream of emailing a stranger.
