Situation:
Assume that your immediate supervisor passes away. His death was not unexpected -- he had been seriously ill for months. You felt very close to him for many reasons, and you feel compelled to write a letter of condolence to his widow, also a personal friend.
The Letter:
Dear Sarah:
Larry's death has saddened me beyond words. Although not totally unexpected, it it still hard for me to accept.
I'm sure you know, Sarah, the enormous influence Larry had on me personally and on my career. He was the first person ever to say to me : "Carl, you have a specail gift. I'm going to do all I can to see that it is developed to its fullest". He then proceeded to do just that, and during our eight years together, he never lost faith in me and was, of course, largely responsible for the success I have achieved.
I suppose most successful people somewhere along the line were singled out by a wise and generous mentor who guided and shaped their careers. Mine was Larry. I shall miss his counsel. Indeed, I do already. Every time I have a hard problem to solve, I ask myself, "What would Larry have done?"
I hope, Sarah, that Emily and I can continue our friendship with you. If ever you feel the need to get away for a quiet rest, out little cottage on Sequoia Lake (which I'm sure you remember) is alway open to you. I've had a key made for you, and it is enclosed.
Affectionate regards,
