From,
Mr and Mrs Filch,

Sydney

To,
Mrs Slim,
Class 5 Teacher,
Dunstan High School,
Sydney

Dear Mrs Slim,
This letter has been drafted for conveying sheer appreciation of the efforts which you have put in for our child, Suzanna. We still remember the day of desperation and despair when we shifted to Sydney and found ourselves in the middle of the school term for our child. We were ominous and felt that the loss of one entire education year of our child is imminent. Even then, we made this last attempt to save the year of our child by approaching your school.
You assured us that Suzanna will prevail through all the studies which have been lagging behind and you would help her by all means. You stood by your assurance and Suzanna excelled in her term examination. We are overwhelmed with appreciation and gratitude for your support. We are assured that our child’s future is in best hand. Thanking you and appreciating your care for Suzanna’s studies,

Yours appreciatively,
Mr and Mrs Filch
