The smoke rose from the chimney stack.
"What a strange world I've just been born into" it said to itself looking down upon the train "and that must be me! Look im so long and powerful! I'm all covered in lights and whistles! I must be very important. Oh I'm so important someone has built a track across the whole world just for me!"
"Why the whole world must have been made just for me! I certainly am important and impressive. Look how I use my free will to choose to go along these tracks!"
The smoke dissipates. It was a full lifetime.
