Are you a different person at home?

We assume we present different faces to our various audiences – that we’re not the same at home as we are at work, for example. In one of the many Second World War histories I’ve read, there’s a photograph of Air Marshal ‘Bomber’ Harris – usually portrayed as stern, even ruthless – playing in his garden with his children. A different person at home, you’re meant to think. And yet, when you look, he’s still in his uniform, rank insignia, medals and all.
