Pray for him

My English tuition teacher is a retired 70 year-old man.As people are getting older,their functions of the organs are getting worse.He is a hardworking man with a caring heart.He has spent his whole life teaching the next generation.When he was 20sth,he started to study about education in English and soon he got the chance to study at overseas which is United States.He never spend one sen of his family's money as his family is quite poor at last time.He depends on his own.He is an independent teacher.He has the responsibility like what my father had for a child.He insisted that he needs to be hardworking for everything because nothing venture nothing gain and he is quite strict which sometimes he is quite stubborn on something.(I don't mean to say that but since everyone is not perfect and honesty is the best policy.I want to express my real feelings about him)Lately,his eyes has a problem of not seeing clearly.He went to check at hospital and the doctor told him his right eye is blocked by something because he has used his eyes too over.He went for an operation.I don't know whether the operation is success?because after doing operation,he needs to put eye drop on his eyes very often like 3 hours a few drops.The very unlucky thing is his eye is not getting better but only pain and tired.He still won't be able to see clearly like last time.And now his left eye also had a same problem.He needs to do operation again for his another eye.Let's pray for him.He will be okay and get back the good vision he used to have.Pray for you,my lovely teacher.
