"John, it's been a month."

"A month? Since what?"

"Since you started doing these sessions again."

"Has it? It feels like it hasn't even been a day."

"That's normal for people going through something like this. Trauma effects how we see time."

"Trauma? You think this is trauma? No, I've been through war. I know trauma."

"What would you call this then?"

" . . . Loss."

"Loss?"

"Loss of hope."

" . . . John, I'm going to give you an assignment."

"An assignment?"

"I want you to write a letter to your friend—"

"Sherlock?"

"Yes. I want you to write a letter to Sherlock every time you need to talk to him. Tell him what's going on in your life, how you are feeling, anything you want to say to him. Just write it down, put it in an envelope and seal it."

"No one will ever see it."

"Exactly."

"Not even the person they are intended for."

"Think of them as letters never sent."
