Some days are better than others

I may be over-thinking this, but when detaching and "not initiating", how do you guys handle social pleasantries like Good morning/Hello/Goodbye with the WW?

Do you not say anything unless they do first (let them initiate) or do you give a "solid but not overly enthusiastic" greeting because that's how awesome upbeat you would interact with a roommate or stranger?
