"This is my note. That's what people do at these times," said Sherlock standing on the edge of a building. He was about to jump.
"When?" asked John, standing a few blocks away. He had a pretty good idea of what Sherlock was going to do, but he refused to accept it. Why would he do this? Sherlock would never commit... John couldn't even think the word. Things had been bad the past few days, but Sherlock would never even think about leaving an interesting case unresolved.
"Goodbye John," Sherlock choked. He knew John would never understand why he was doing this. A tear escaped his eye. He jumped.
"Sherlock!" John screamed as loud as he could. There were screams. John knew Sherlock was falling.
"I love you." he whispered into the phone, sobbing. Sherlock may not have heard it, but John still wanted him to know, even if it was his last few moments.
Sherlock smiled. This last thought, those last words made his death a little happier.
When a few moments had passed since John spoke, he thought he heard, "I love you, too."
