         After finishing my shopping, I headed for the checkout
counter but was blocked in the narrow passage by a young
man that appeared to be about sixteen years old. I wasn’t in a
hurry, so I patiently waited for the boy to realize that I was
there.
After a little while, he waved his hands excitedly, in the air and shouted in a loud voice, Mommy, I'm here．Mommy, I'm here． It was obvious now, he was mentally challenged．Suddenly, he turned and saw me standing so close to him．His eyes widened and watched me surprisingly．He turned and saw me standing so close to him. His eyes widened and watched me surprisingly. I stepped back and asked, Hey, buddy, what’s your name? My name is Denny and I'm shopping with my mother, he responded proudly．Wow, I said, that's a cool name．I wish my name was Denny, but my name is Hal． Hal like Halloween? he asked．Yes, I answered．How old are you, Denny? How old am I now．Mommy? he asked his mother as she came over from the next passage．You' re fifteen years old, Denny; now be a good boy and let the lady pass by． I continued to talk to Denny for several more minutes about summer vacation, bicycles and school．I watched his brown eyes dance with excitement．
As we were talking, he suddenly ran toward the toy section．
Denny's mom thanked me for taking the time to talk 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, Denny is a blue rose and if I didn' t stop and smell that rose with my heart, I would miss a blessing from God．
She looked more puzzled．I told her that there are plenty of red, yellow and pink roses in God's garden, however, blue roses are very rare and should be appreciated for their beauty and distinctiveness （特殊之处）．Denny is such a blue rose in God's garden．
