Their first argument is that when we were 1 we used to look after the older people in our community and help them. They also say that young people today don't care about anything or anyone. 2 , I think the reason why we looked after older people was that we had no 3 . People had to live with their parents and grandparents because they had no money. Young people today earn more and have more freedom to live where they want. 4 this, I think that they are still interested in older people. For example, young people often 5 to help me when I get on and off the bus with heavy shopping. Their second argument is that in our day we didn't 6 to be given jobs-and that young people now don't look for jobs, but just complain about unemployment.
