Wishes, Desires

Sometime after Bernie died, his widow, Rachel, was finally able to speak about what a thoughtful, considerate, and wonderful man her late husband had been.
"My Bernie thought of everything", she told them. "Just before he died, he called me to his bedside. He handed me three envelopes. 'Rachel', he told me. 'I have put all my last wishes in these three envelopes. After I am gone, please open them and do exactly as I have instructed. Knowing you'll do this, I can rest in peace'."
"What was in the envelopes?" her friends asked.
"The first envelope contained $5,000 with a note, 'Please use this money to buy a nice casket'. So I bought a beautiful mahogany casket with such a comfortable lining that I know Bernie is resting very comfortably.
"The second envelope contained $10,000 with a note, 'Please use this for a nice funeral.' I made Bernie a very dignified funeral."
"And the third envelope?" asked her friends.
"The third envelope contained $25,000 with a note, 'Please use this to buy a nice stone.'
At that point, Rachel held up her hand and pointed to her ring finger, on which was a gorgeous diamond ring.
"So?" said Rachel, "You like my stone?"
