    My family was gathered for a barbecue when the discussion arose about a celebrity who earned a large amount of money. The major criteria for receiving millions of dollars seem to be determined by how much the audience will pay to watch the performer achieve.

    The discussion led to a sudden self-questioning. Why did I choose teaching for a career? I half-listened to their conversation as I pondered the answer.

    I remembered my three children watching me spend nights planning for my class. I remembered how they intently listened to my frustrations concerning materials, procedures and the amount of responsibility that seemed to endlessly be thrust into the laps of classroom teachers. I remembered when it came time for each of my own children to choose a profession. How I waited to hear if any had plans to follow Mom into teaching. Long considerations held no mention of anyone becoming a teacher.

    Dessert was being served, and everyone was still involved in the discussion of the enormous salary of one individual, when the phone rang. My husband handed the phone to me.

    “Hello, this is Bonnie Block,” I said.

    “Is this the Bonnie Block who used to teach kindergarten?”

    A nervous sensation swelled in me, and my mind raced with memories of those days long ago.

    “Yes!” I exclaimed with a lump in my throat. It seemed like forever as I waited anxiously to hear what the caller would say next.

    “I am Danielle—Danielle Russ. I was in your kindergarten class.”

    Tears of surprise and joy rolled down my flushed cheeks.

    “Yes,” I uttered softly as I remembered that darling, wonderful child.

    “Well, I am graduating from high school this year, and I have been trying to find you. I wanted you to know what a difference you made in my life.”

    She proceeded to give details. My influence on her wasn’t limited to kindergarten but remained a strong motivating force when she needed a coach to help her meet a challenge. “I pictured you praising and encouraging me all the way.”

    Why choose teaching?

    The pay is great!

—______are you from?

—I'm from China.

       邻之人有鸡夜呜，恶其不祥，烹之。越数日，一鸡旦而不鸣，又烹之。已而谓予日：“吾家之鸡或夜鸣，或旦而不鸣，其不祥奈何？”予告之日：“夫鸡鸣能不祥于人欤？其自为不祥而已。或夜鸣，鸣之非其时也；旦而不鸣，不呜非其时也，则自为不祥而取烹也，人何与焉？若夫时然后鸣，则人将赖汝以时夜也，孰从而烹之乎？”又思日：“人之言默，何以异此？未可言而言，与可言而不言，皆足取祸也。故书之以为言默戒。”
【注】①时夜：司夜，指打鸣报晓。时，掌管。
