How does Sherlock Holmes treat Dr Watson?

Holmes treats Watson like he would treat any other person. Although Watson isn't the brightest bulb in the bunch, Holmes treats him very well. For instance, in the beginning of the book Sherlock Holmes and the Hound of the Baskervilles Watson proposes evidence/clues about a "walking stick" that they found in Holmes den. Watson's clues are way off. Holmes (who already knew who's walking stick it was, and who also knew that every one of the clues that Watson proposed was indeed incorrect) did not say a Word to him. So that tells you that Holmes is very good to Watson.
