> **The patronizing "we"**
> 
> The patronizing we is used sometimes
> in place of "you" to address a second
> party, hinting a facetious assurance
> that the one asked is not alone in his
> situation, that "I am with you, we are
> in this together". A doctor may ask a
> patient: And how are we feeling today?
> This usage is emotionally non-neutral
> and usually bears a condescending,
> ironic, praising, or some other
> flavor, depending on intonation:
> "Aren't we looking cute?"
