Letter: 31st August 2006 To Class Teacher, Grade II, National Public School, New York. Dear Madam, I am XXX and I am writing this letter to inform you that my son, XXX studying in your class was diagnosed with chicken fox and advised to take bed rest till she gets cured completely. I am fearing to send her to school as chicken fox is a communicable disease. I kindly request you to grant him leave till he gets completely cured and also to stay under continuous medical supervision to get quicker recovery. Thanks for considering my request. Thanking You, Yours Sincerely,
