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?"
