"Please Watson?" Sherlock pleaded as Watson walked away from him.
"No Holmes! I don't want to!" Watson said to Sherlock over his shoulder.
Sherlock followed Watson into the sitting room and continued to bug Watson until Watson turned to face him.
"Holmes, I don't want to learn about chemical reactions!"
"But think of all the ways it could help you!"
Watson threw his hands up and cried, "I am a doctor, not a chemist!"
