Yes; I would like to be famous; because it feels good to be admired and loved by every one and famous people are also very often rich. I think famous people have to be aware of their images and the way they act and perform. Young people are interested in them and they want to be like them; wear the same clothings and dance or sing like them; for instance. So popular people can have a positive or a negative influence. It depends on their behaviour. It is good that we can watch the daily news at any time we like. That keeps us well informed about all special events and changings. We can prepare ourselves when it will rain cats and dogs. We can help each and make the right decisions.
