In my living room，there is a plaque (匾) that advises me to“Bloom (开花) where you are planted.” It reminds me of Dorothy.I got to know Dorothy in the early 1980s，when I was teaching Early Childhood Development through a program with Union College in Barbourville，Kentucky.The job responsibilities required occasional visits to the classroom of each teacher in the program.Dorothy stands out in my memory as one who“bloomed”in her remote area.

Dorothy taught in a school in Harlan County，Kentucky，Appalachian Mountain area.To get to her school from the town of Harlan，I followed a road winding around the mountain.In the eight­mile journey，I crossed the same railroad track five times，giving the possibility of getting caught by the same train five times.Rather than feeling excited by this drive through the mountains，I found it depressing.The poverty level was shocking and the small shabby houses gave me the greatest feeling of hopelessness.

From the moment of my arrival at the little school，all gloom (忧郁) disappeared.Upon arriving at Dorothy’s classroom.I was greeted with smiling faces and treated like a queen.The children had been prepared to show me their latest projects.Dorothy told me with a big smile that they were serving poke greens salad and cornbread for“dinner”(lunch)．In case you don’t know，poke greens are a weed­type plant that grows wild，especially on poor ground.

Dorothy never ran out of reports of exciting activities of her students.Her enthusiasm never cooled down.When it came time to sit for the testing and interviewing required to receive her Child Development Associate Certification，Dorothy was ready.She came to the assessment and passed in all areas.Afterward，she invited me to the one­and­only steak house in the area to celebrate her victory，as if she had received her Ph.D.degree.After the meal，she placed a little box containing an old pen in my hand.She said it was a family heirloom (传 * * )，but to me it is a treasured symbol of appreciation and pride that cannot be matched with things.
