    I got your letter dating April 20 the day before yesterday. All of our family greatly delighted to learn that you are getting on well with your subject. How time flies. After a few weeks, you’ll finish middle school. How pleases us most is that you have made your mind to attend college examination this summer. How wonderfully it is! Dad, as well as Mom and I, are always with you. We hope you to make better use of your time. The fuller preparations you make, the sure of success you’ll be.
