Pumping gas the other evening after coming home on the late side, a woman came bouncing out of the convenience store, looked at me as she passed, and yelled "SMILE!"   She was judging me.  I wondered if I go around looking like a grouch, though I have to admit that at that time I was feeling a little grouchy.  It must have showed.  So I smiled back, and suddenly felt less unsmiley.

Then Friday morning, sitting in the train where everyone was very quiet, either reading or sleeping, the conductor bounced into our car and said "smile everyone, it's just work!"

All of the sudden smiling is becoming a big deal.  I better get on the bandwagon.
