Input: Sherlock Holmes:  I owe you a bit of an apology . I attempted to express my concern for you last night , but my thoughts were distorted by the lens of my own needs . It was not optimally done .
Dr. Joan Watson: Oh , that 's okay .
Sherlock Holmes: What I was trying to say was that one of the things I 've gained from our collaboration is a working definition of the word friendship . Friendship , I 've come to believe , is most accurately defined as two people moving towards the best aspects of _ one _ another . It is a relationship of mutual benefit , mutual gain . Another thing I 've learned is that my isolationist tendencies are decidedly not my best quality . I am not a better person because of a lack of connection . So , I think the healthy thing is for you not to move in my direction . In fact , quite the opposite .
Dr. Joan Watson: That 's worth thinking about .
