I got caught talking to myself in the car this morning. Has that ever happened to you? I was sitting at a set of traffic lights yakking to myself with the window down when I spied a pedestrian, crossing in front of me. I did the only dignified thing I could do and pretended to be speaking on a handsfree mobile.
"Yeah, er, OK I'll call you back when I get there, bye!"
The worst thing was, and this is the thing that confirms how tenuous my grip on reality is, I was having an imaginary argument with myself, and I was losing.
