I was at the post office early that morning, hoping to be in and out in a short while. Yet, I    myself standing in a queue that went all the way into the hallway. I had never seen so many people there on a weekday. It seemed someone might have made an announcement,    customers to carry as many packages as they could. I also needed to have my own package    . The queue moved very slowly. My patience    and I got annoyed. The longer it took, the angrier I became. When I got to the counter finally, I finished my    quickly and briefly, and then walked past the queue that was now extending past the front door.

Had I looked like that? Her body language said that she was having a      day. My anger melted away. I wished I could wrap her in a      but I was a stranger.

I saw her take a deep breath. Her pace slowed and she smiled back at me as we passed each other.
I continued to smile all the way to my car. Wow, it’s amazing    a simple smile can do.
From then on, I became aware of people’s     and my own, the way we show our feelings. Now I use that    every day to let it      me that when facing the world, I can try a smile.
