One of my favorite things I’ve realized I do lately is whispering when I’m exchanging 'goodbyes' or 'hellos' with someone and they are not within hearing range.

I whisper because, in my mind, that's the volume they are getting. And what do I get? Well, most people I do this too be smart and know how to economize efforts so they do not even mouth words, they just nod; an advanced technique, son.
