It’s quite a popular pastime – a time-spending go-to when you’ve run out of people to call or text and you still have battery life left on your phone. Or when you want proof of having been somewhere or with someone of note.
The smart phone didn’t invent selfies, it just made them easier. “You call that a knife? That’s not a knife. THAT’s a knife.”
Now that’s what I call a “selfie”. If I hadn’t given up the violin, I could be a string quartet.
