Happiness defined

I was in a difficult situation the other day.

I was in a tea room where I could either plug my iPhone into a wall socket (but couldn't get a signal in this seemingly lead-lined dead space) or I could get a signal on my iPhone, but nowhere near a wall socket.

I have thus stumbled upon the modern version of happiness, which used to be defined as Dinner and a Show.

The more modern version is Power and a Signal.
