I know one family and it ised to be very poor. There are four people in it: a mather, a father and two boys. Parents used to wake up early, work in a plant and make little money. Time passed, they got old and their children grew up and married. Both of them have good careers and make a lot of money. They have bought a good country house for their parents and provide their parents with things they need on a regular basis. So, now these old people are happy and enjoy their lives because they brought up good children. Now they can say: Finally, the sun is shining down our street too!
