Dear Sir or Madam,

I am writing about a serious concern with the swimming coach who recently took charge of my son's training. My son, who is ten years old, has been enrolled at your swimming club since he was five, and for all five of those years his coach was Priya, who sadly became seriously ill and had to give up coaching a short while ago. This greatly upset both my son and me, because Priya was an exceptional instructor, and we sincerely hope she recovers soon.
