As the burgeon of model lifestyle, people are equiped with high tech phones, televisions, and computers. The way of working and the choices of social activities changed a lot as well. Under these circumstances, some people argue the advices from our grandparents, the representitives of old people, have no use for their grandchildren because the world changed a lot during the past fifty years. However, I disagree with this statement, because the essence of life and relationship between humans did not change with the advance of technology.First, grandparents can tell a great amount of useful life experiences. Although these life experiences cannot be fully understood without the wash of time, they can still be helpful for teenagers who stand at the crossroad of life. Take me as an example, When I was young, I used to skiping class and be addicted to videl games. Of course my grades at middle high are low. It is my grandfather who teach me to study hard, go to college and be a man. He described his eagerness of going to universities when he was a boy, but he musst drop from school because of provety. After hearing his story, I was touched and determined to achieve his dream through my hand. I decided to take the responsibility of being a good son. Thats the story of my grandfather and I. Grandparents' have abundant lesssons about life. How to be a man, how to plan our life, and why should we keep a long outlook, these would never fade away with the past of time.Second, grandparents can tell us how to become a moral person with high standards and how to cultivate good characters.I have seen many cases where young children did not listen to their grandparents buried themself finally. One of my childhood friend, jack, used to drinking  a lot everyday and being addicted to drugs. His grandparents hurts broke. They advised him everyday but jack did not accept it. Even oneday jack got angry and almost beated his grandparents. Finally jack was sent into prison because of drugs. His entire life was done. And for me , thanks to my grandparents, they taught to how and why to be a good person with integrity, pesistence and elegance. These help me make many friends in the school and workplace, which contributed much to my career.we have to admit that grandparents do lose to grandchildren in some cases. My sister often teach our grandparents how to use iphones and ipad to get in touch with us. She even guide them to download interesting Apps to have fun. But in the matter of life experience and personalities, their suggestions are still shineing.
