     Barditch High School decided to an All-School Reunion. Over 450 people came to the event. There

were tours of the old school building and a picnic at Confederate Park. Several former teachers were

on ands to tell stories about the old days. Ms. Mabel Yates, the English teacher for fifty years, was

wheeled to the Park.

     Some eyes rolled and there were a few low groans(嘟囔声)when Ms.Yates was about to speak.

Many started looking at their watches and coming up with excuses to be anywhere instead of preparing

to listen to a lecture from and old woman who had few kind words for her students and made them work

harder than all the other teachers combined.

     Then Ms. Yates started to speak:

     "I can't tell you how pleased I am to be here. I haven't seen many of you since your graduation, but

I have followed your careers and enjoyed your victories as well as crying for your tragedies. I have a

large collection of newspaper photographs of my students. Although I haven't appeared in person, I

have attended your college graduations, weddings and even the birth your children, in my imagination."

     Ms. Yates paused and started crying a bit. Then she continued:

"It was my belief that if I pushed you as hard as I could, some of you would succeed to please me and

others would succeed to annoy me. Regardless of our motives, I can see that you have all been

successful in you chosen path."

     "There is no greater comfort for an educator than to see the end result of his or her years of work.

You have all been a great source of pleasure and pride for me and I want you to know I love you all

from the bottom of my heart."

     There was a silence over the crowd for a few seconds and then someone started clapping. Tee

clapping turned into cheering, then into a deafening roar(呼喊). Lawyers, truck drivers, bankers and

models were rubbing their eyes or crying openly with no shame all because of the words from a long

forgotten English teacher from their hometown.
