My brother gave a hat to my father for Christmas. In my father's mental state, anything he gets is going to be a confusion until he can safely 'lose' it or file it away out of sight. He needs simplicity and new things threaten the equilibrium of his mind's event horizon.
However, a new hat was an opportunity to get a rise from my mother. It worked and the incredulous verging on censorious look coming over her face was enough to make me reach straight for the camera and do this instant self-take.
