                                                                  Mickey's Goal

     Last night was the last game for my eight-year-old son's soccer team. It was the final quarter. The score

was two to one, my son' s team in the lead. Parents surrounded the playground, offering encouragement.

     With less than ten seconds remaining, the ball suddenly rolled in front of my son's teammate, Mickey

O'Donnel. With shouts of "Kick it!" echoing across the playground, Mickey turned around and gave it

everything he had. All around me the crowd erupted (沸腾). O'Donnel had scored!

     Then there was silence. Mickey had scored all right, but in the wrong goal, ending the game in a tie. For

a moment there was a total hush. You see, Mickey has Down syndrome (综合征) and for him there is no

such thing as a wrong goal. All goals were celebrated by a joyous hug from Mickey. He had even been known

to hug the opposing players when they scored.

     The silence was finally broken when Mickey, his face filled with joy, hugged my son tightly and shouted,

"I scored! I scored. Everybody won! Everybody won!" For a moment I held my breath, not sure how my

son would react. I need not have worried. I watched, through tears, as my son threw up his hand in the

classic high-five salute and started chanting, "Way to go Mickey! Way to go Mickey!" Within moments both

teams surrounded Mickey, joining in the chant and congratulating him on his goal.

     Later that night, when my daughter asked who had won, I smiled as I replied, "It was a tie. Everybody

won."
