My father was a keen baseball fan. He loved to play whenever he could. Usually Dad took me out to the park and pitched balls for me to hit.
One day at the park, a woman pushing a young boy in a wheelchair stopped to watch us play. My dad was (looking) over to them in a flash to ask if the child could join our game. The woman explained that her son had polio and wouldn't be able to get out of the chair.
That didn't stop my dad. He placed the bat in the youngster's hand, pushed him out to
home plate and assisted him in holding the bat. Then he yelled out to me,
"Anne, pitch one in to us."
I saw the delight in the boy's eyes, so I aimed at the bat and let the ball fly. The ball made contact with the bat with an assist from my dad and the child screamed with joy. As I turned,
I heard my dad singing Take Me Out to the Ball Game.
An hour later we all left the field, very tired but very happy. Dad told (his) mother to bring the boy back next Saturday and we would play another game.
Dad and I were at the field (on) the next Saturday but the mother and son never came. Twenty years passed, with my dad gone, I had very mixed emotions about leaving the neighborhood. Before moving, I decided to take one last walk around the park where Dad
and I had spent so many happy moments. Two Little League teams were on the field just about to start a game. I felt the sting of tears in my eyes as I watched the children play the game.
"Jeff, protect your base," one coach yelled. I cheered the runner on when the ball was
hit far into the outfield. The coach turned and smiled, "I never thought I'd ever be a coach playing on this field. You see, I had polio as a child and was restricted to a wheelchair.
Thanks to a man's assistance, I was able to hit the ball and hear him singing the song
Take Me Out to the Ball Game. I believe that experience gave me the desire to walk again
I hope that some day I'll look up in the stands and see that man and his daughter again.
I sure would like to thank him."
我的父亲是一个棒球迷。他一有空就要打。通常爸爸带我去公园, 掷球让我打。
一天在公园里,一个女人用轮椅推着一个男孩停下来看我们玩。我爸爸在掷球的一瞬间问孩子是否可以加入我们的游戏。女人解释说,她的儿子患有小儿麻痹症而无法摆脱轮椅。
这并未让我爸爸停下来。他将球棒放在这个年轻人的手中，把他推到本垒的位置上，帮助他握住球棒。然后他对我喊：“安妮, 掷球。”
我看到男孩的眼中的喜悦, 所以我瞄准球棒把球掷出去。在我爸爸的帮助下，球碰到了球棒， 这个孩子也怀着喜悦而尖叫。当我转过来时, 我听到我长起“带我出去来比赛”这首歌。
一个小时后我们离开了球场, 虽然很累但我们都很高兴。爸爸告诉他母亲，下个周六带男孩再来玩。但这个母亲和儿子都没来。
二十年过去了, 我的爸爸离世了, 我怀着非常复杂的心情也要离开邻里。在搬家之前,我决定在我和爸爸度过很多快乐时刻的这个公园做最后一次散步。球场上。两个小联队正准备开始比赛。当看到孩子们要比赛时，刺痛的眼泪在我眼睛中打转。
“杰夫,保护你的球垒,”一位教练喊道。当球被击倒场外远处时， 我对跑垒的队员加油鼓劲。
教练转身对我笑着说,“我从来没想过我能成为一个教练在这里比赛。你看, 我在小孩时得了小儿麻痹症,只能被困在轮椅上。感谢一个人的帮助，,我能够击球并听到他唱这首歌“带我出去来比赛”
我相信这个经历给了我重新行走的信念。 我希望有一天我会站在看台上, 再次见到那个男人和他的女儿。我一定要感谢他。”
