Training Sherlock

Sherlock seems to forget that he's actually alive sometimes, that he's bound by the same rules that all of humanity is, however dull he may find them. It boggles John's brain. Irritates him at first, then boggles him, and, after this long, it just makes him sigh. It's a bit like training a dog. Or teaching a child. [Fluff featuring stubborn Sherlock and ever patient John]
