Dear Sir or Madam,

I am writing to raise a serious concern regarding the skating coach who has recently assumed responsibility for my son's training. My son, who is nine years old, has been enrolled at your figure-skating club since the age of four. Throughout those five years he trained under Daniel, who regrettably fell seriously ill and had to give up coaching not long ago. This news distressed both my son and me a great deal, because Daniel was an exceptional instructor, and we sincerely wish him a rapid recovery.
