Sherlock lay on the couch in 221B in full concentration. John came home with the shopping and chose to ignore his friend.
"This is hard. The hardest case I have ever endured." Sherlock said.
John looked up. "What?"
"I've thought of many theories but none of them are right. This is the biggest problem I have ever faced."
"What is the problem, Sherlock?"
"I must be missing some small miniscule detail that could solve the whole problem. How do I not see what is probably right in front of me?"
"Sherlock, you aren't giving me anything to go on. Are you in trouble?" John was confused by Sherlock's behavior.
"I am determined to solve this. After all, I am brilliant."
"Sherlock, I'm getting worried now."
"Nothing gets past me. Ever. I have to investigate again."
"Is it something I can help with?"
"I need to find someone with experience in relationships and has had experience in sentiment. If I find that person, I can solve this case."
"Sherlock, I have that kind of experience."
Sherlock finally took notice of John. "Oh, hello, John. I need your help on a case. You are just the man for the job."
"What was the problem? A woman who was killed by an ex-boyfriend? Something like that?"
"I need a way to ask Molly Hooper out."
John rolled his eyes. "And I thought you were really in trouble."
"Me? John, I am never really in trouble."
