Are you good at learning English grammar? What do you think about learning grammar when studying a foreign language?
I was a young English teacher in a middle school. One day, a student asked, "Mr. Lewis, what is the difference between a period（句号） and a comma（逗号）?" I hated these grammar rules and hardly understand them myself. As I looked at the textbook, I knew that even if I told this student all the different rules about commas, he wouldn't remember them.
I was also in no mood（心情） for a long lesson. My mum had died just a few short weeks ago. I missed her so much. All I wanted to do was stay in bed, but my own young family was living a difficult life and I knew I had to take every day of work I could.
I looked at the textbook again but couldn't read it because my eyes were so watery. All at once, however, I got an idea. "A period is the end of a sentence or a thought," I said, "A comma, on the other hand, is just a short pause（停顿） before the sentence continues on." When I finished saying this, my heart suddenly felt lighter. I smiled and thought of my mum continuing on in a place much brighter and happier than the one I was in now.
That little moment of light helped me as I continued to miss my mum over the months and years to come. Recently I remembered it once again when I saw this sentence in a book I was reading: "Death is not a period, only a comma."
Our lives are a sentence and a story that goes on forever. Our time here is only a part of it.
