I"ll write about the video, the Kinematograph.
An old man who was inventor and tried to color film.
One day, his wife said,"Your invention is enough, it 's pretty nice." to him.
However, he could not give up more improvement. He was crazy for his invention all day long, but he should have realized his wife tended to be a sickness. Finally, he found his wife falling on the floor. He made his invention be perfect, instead of it, he lost the most important person forever.
This story show us our lack of communication. Today, there are many technological things, so we do not need to communicate with people directly. However, I think it is more important to communicate with a person face to face.
