This “simple” word can make all the difference and if you don’t hear it from your two sides maybe it’s time you become the catalyst. Yes, everyone should warmly greet Y-O-U but why wait when you have your own mouth and tongue? This is especially true for those who have a tendency to feel secluded from the room. If you start you also can finish so think of the power you set before you worry about what others should do. It’s a simple word but it can make all the difference in the world especially for one who has not heard it enough.
FOOTNOTE– When leaving you might want to make sure everyone knows as well.
