Um, Why?

 This week has been a string of meetings, errands, appointments, and other out-of-the-house stuff.  The places that I had to go into (as in when things couldn't be handled at a drive-thru window) when business was concluded, I was given hugs.  I returned them, as one most often does, but, how come those people --- some of whom I've never gotten past a handshake with --- feel the need to embrace me?  Am I emitting needy vibes?
