That day, my legs hurt, I was tired. The corridor in the tube seemed interminable.
I took out my camera and shot pictures.
They showed how long that road felt for me, they speak to me still today. And they spoke to more then 300 who looked at it and 10 who 'favourited' this.
It was worth using it.
So it is with a story or comedy routine. We can later make fun, or recount what happened. Share it. We transmit not only what happened to us that day, but feelings we all share.
