With the flu in mind I've been watching people interact with each other. All the hand shakes, hi 5's, hugs.
The tv had a Halloween store segment and people were trying on rubber masks, checking themselves out, and putting them back on the rack.
I thought of the tradition of blowing out birthday candles.
How some churches share the communion goblet.
Public restroom door handles.
Sick people in denial and won't go home.
Donald Trump doesn't like to shake hands but prefers the Japanese tradition of bowing.
Maybe it's time to rethink our habits.
Tracers work both ways.
