I spent the rest of the afternoon reflecting on the phenomenon of Emoji. I thought about the emojis I used, safe in my comfort zone, the boring ones: the wink, smile and, sometimes, a sad face. Before then, I’d never thought much about whether there were other emojis, or even where they came from. I tried to recall when I had first become aware of them. I struggled. One day they just seemed to be there, all at once, as if they had been dropped out of the sky and into our smartphones. Today emojis really do seem to be everywhere. But back in early 2015, people were just starting to use them in numbers. And I had to admit it, I didn’t have a clue what some of them were supposed to convey. For instance, what did that one of the dancing twin girls with bunny ears mean?
