15 years spent in the field of education has provided me with treasured (珍爱的) moments. One of the most priceless happened when I was teaching second grade, 10 years ago.
In May of the fourth quarter, I decided to 1 something special for the children: A Mother's Day tea. We put our 2 together to come up with ideas of how to 3 our mothers. We decided to hold our tea the Friday before Mother's Day. Each child took home an invitation and I was 4 to see that every mother was planning to attend. I even invited my own mother.
Finally, the 5 day arrived. At 1:45 that afternoon, each child lined up at our classroom waiting for the 6 of his or her mom. As it got closer to starting time, I looked around and my eyes quickly found Jimmy. His mother hadn't 7 and he was looking anxious.
I took my 8 by the hand and walked over to Jimmy. "Jimmy," I said. "I have a bit of problem here and I was wondering if you could 9. I'm going to be really busy. I was wondering if you could keep my mother company while I'm busy."
My mom and Jimmy sat at a table with two other mother-and-child 10. Jimmy served my mom her treats, presented her with the gifts I had made, and pulled out and pushed in her chair, just as we had practised the day before. 11 I looked over, my mom and Jimmy were in 12 conversation.
Now, 10 years later, I work with students of all ages, educating them about the environment. Last year, I was at a high school on a field trip, and there was Jimmy. When Jimmy made sure we were the last two, he said, "Remember our Mother's Day 13 we had in second grade? Thanks for all you did for me, and thank your mother, too. No one knew my mom didn't 14!" I 15 my work with a hug from a teenage boy who had probably stopped hugging teachers years ago.
