Today’s column addresses the awkwardness of repeated hallway meetings in the workplace:

During my workday I make multiple trips between my office and other rooms in the building. I often pass the same people in the hallways several times. After the first direct greeting each day, I feel awkward if I do not say something to acknowledge them as we pass. I sometimes have something business-related to mention, occasionally something witty, but always a nod and smile. Is the last response acceptable, as multiple “hellos” each day seems weird?

I tweeted earlier today that this question is “very Simon/Sacha Baron Cohen.” The Baron Cohen cousins are among the world’s most renowned scholars and practitioners, respectively, of the awkward moment. Mr. Improbable explains it all for you.
