When shopping in a store,I met a young man．When I saw the boy waving his hands excitedly in the air and shouting in a loud voice,“Mommy,I'm over here．”I knew he was mentally(精神上)challenged．
I asked his name and he said proudly,“My name is Denny and I'm shopping with my
Mother.’’ “Wow,”I said,“that’s a cool name!How old are you,Denny?”
“How old am I now．Mommy?” he asked his mother．“You’re fifteen years old,Denny；now be a good boy and let the man pass by．’’I continued to talk to Denny for several more minutes about summer,bicycles and school.I watched his brown eyes dance with excitement because he was the center of someone’s attention.
Denny’s mom thanked me for talking with her son．She told me that most people wouldn’t even look at him.much less talk to him…I told her that it was my pleasure and then I said something I have no idea where it came from：
“There are plenty of red.yellow and pink roses in the garden．However,‘Blue Roses’ are
very rare and should be appreciated for their beauty and distinctiveness(独特性)．Denny is a
‘Blue Rose’ and if someone doesn’t stop and smell to that rose with their heart and kindness,then
they’ve missed a chance to appreciate the beauty．’’
She was silent for a second,and then went away with tears in her eyes．
