(Suppose your brother has become insincere and inattentive to his study. He keeps himself with bad company and whiles away his time. Now write a letter to your younger brother advising him to be sincere and attentive to his study.)

My Dear XYZ (Name),
It was quite long since we received any letter from you. Yesterday your progress report of Second Terminal Examination from your principal reached us. We have become very shocked to know from the report that you have failed almost in all subjects.
We had although a high opinion about you, but you have greatly disappointed us. I am sure that you keep bad company and while away your time. Remember time once gone can never be got back and bad habits once formed are not easy to give up.
I like to remind you that we belong to a middle-class family. Our educational expenses are borne with great difficulty. We have to stand on your own feet. We should not do anything which pains our parents. You should know that only the fittest can survive. Time is not long ahead of when you will have to earn. Without proper education, you cannot expect to get a good job. Student life is the proper time to get proper education. So you must be sincere and regular to your studies. You must learn to value time and give up your irregularity. At the same time, you have to give up bad company.
