I was at the post office early that morning, hoping to post a letter at the start of a busy day. Instead, , I found myself standing in a queue that went all the way into the hallway.I had never seen so many people there on a weekday. The queue moved very slowly.My patience ran out and I got angry. When I got to the counter finally, I finished my business quickly and briefly, and then walked past the queue that was now extending past the front door. Thinking I was going to be late for my dentist  appointment, I was scowling   as I headed into the parking lot. A woman was coming across the lot in my direction.She was walking with determination, and each step sounded very heavy.I noticed that she had a scowling on her face. Her body language said that she was having a really terrible day.My anger disappeared.I wished I could wrap her in a hug but I was a stranger. So I did what I could in a minute before she hurried past me-I smiled.In a second everything changed.She was surprised. Then her face softened and her shoulders relaxed.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 what a simple smile can do.From then on, I became aware of people's expressions and my own, the way we show our feelings.Now I use that awareness in my everyday life to let it remind me that when facing the world, I can try a smile. Why did the writer become angry at the post office?
The worker there was impatient. She failed to post her letter. Some people cut in line. She had to wait for a long time.
