趟过小河是故乡

宋长征

(1)你坐下来,时光在眼前静静地流淌。你想抓住些什么,时光却在指缝中溜走。阳台上的雏菊花开了,黄的白的和粉的交错在一起。你想起了故乡,小河畔的野雏菊开得正浓。可阻断你的到底是什么,总也说不清,你只知道那满坡的春天啊,还有母亲的羊群都在小河里流动。而你,说不清的距离像横亘在生命里的一场雾霭,和故乡遥遥相望,任脸颊清泪两行。 

(2)梦里,母亲的捣衣声孤单地响起,溅起的水雾打湿了她的发髻。浣衣的石板在水流里青着,泛起一些岁月凝集的韶华。青石板有泪么?那淙淙的河水不回答,也不怎么匆忙,静静地流淌。

(3)一个背影和一头金色皮毛的老牛在下游的岸边伫立,影子被清澈的河流带走,只留下一些湿淋淋的回忆,在今夜或者某夜的月光中上岸。父亲的那头老牛,金黄色皮毛的光泽在夜色中闪耀,照亮了潺潺的流水。

(4)岸上的野雏菊兀自开着,母亲的羊群只剩下小小的一朵,在天上飘,随风,随着时光,再也来不及在明净的水面上打量一下自己的模样。

(5)你为什么忧伤?你的远行不过是从此岸跨越到彼岸的距离。尽管你走时,母亲撩起衣襟在门板后擦了擦眼睛,然后让你踏着她的目光上路,涉水而过。那一天,风正紧,雨斜织在小河的上空,如烟,如雾,网织着故乡的模样。

(6)季节啊,有时也像一条小河,先是用绿色把你的思念串起,就成了一挂风铃,叮当着童年的时光。河水像母亲的温柔,从腋间,从脚趾缝里,从甜蜜的心窝子里轻轻流淌。你快要醉了。母亲的气息有春天的香甜,舌尖上,睡梦中,咂了又咂;眼眸里,摇篮中,要了还要。——你是喂不饱的小花狗呢!母亲眉眼弯弯,用嗔怪戳着你的额头。

(7)叛逆的河水总在夏天暴涨,你不用再牵谁的手就能轻松跨过漫水的小桥。你自信长了青蛙的蹼掌,扎个猛子就能从此岸泅到彼岸。父亲的眼里是坏坏的笑,专门倚在老牛的身上等你,看你呛水的样子。

(8)秋天了,谁在岸上等你?野雏菊向着太阳,擎出盛满了子实的托盘。可是一个又一个秋天啊,你让等待的人花白了鬓发,直到那头有金色皮毛的老牛牵着父亲走进了夕阳,你还在彼岸徘徊。

(9)流泪的母亲啊,在河边捣衣,遥远的布谷声声,再也不能惊醒她的鼓膜。她浑浊的双眼痴痴地望着清水柔波,每一条游鱼的自由自在都值得这样每天为之祈祷。河岸上的野雏菊开了,河岸上的野雏菊败了;那个和她一起耕耘岁月的人被一头金色毛皮的老牛牵走了……

(10)她的青石板没有了棱角,每一缕流水轻轻走过,再也打不出旋涡。

(11)布谷鸟停止了歌唱。在青石板上敲打岁月的母亲不得不这样认为,然后依然用力,希望“嗵嗵”的捣衣声可以传得更远。----从此岸到彼岸。

(12)故乡那条弯弯的小河,玉带般缠绕着一些熟悉的身影。你定定地凝望今晚夜空里的月亮,月亮那么明媚又充满哀伤。你知道今夜月光如水,就如流年似水一样不能紧紧把握。还不如那条小河,轻轻一掬,就捧起一汪晶莹。可是你的渡口呢?即便是“野渡无人”不是也希望有一艘能载动清愁的小船么?好让你从此岸到彼岸,再看那野雏菊花开的模样。

(13)“快回、快回”,布谷鸟的叫声比任何时候都要嘹亮,能穿透夜色,也能穿透心房。你还要踟躇么?母亲的鬓发在窗外飘过他乡的夜空,带一片野雏菊花开的美丽,来看你。你的心开始跳跃了吗?一些失落或忧伤在那个等待的怀抱里可以无所顾忌地释放。她会嗫嚅着嘴唇,哽咽着喉咙,为你擦去思念的泪光;她会揽你入怀,就像小时候,端详着你的脸颊,读出一生的幸福。

(14)从此岸到彼岸,每一处都是渡口。每一个渡口都停泊着一艘写着故乡的小船,在等你,趟过小河是故乡……

When I was a child, I was shocked at the idea that my sisters could be my best friends. Now, I wouldn’t have it any other way. At the time, the idea of my two sisters being my closest friends seemed strange to me. We fought all the time over toys, food, attention, what to watch on television—you name it, and we quarreled about it at some point. How could my sisters be my best friends? They weren’t the same age as I. We all had our own friends in school.

My mother never let the three of us forget that sisters are lifelong friends. Her wish like most parents’ was to give us something that she never had. Growing up as an only child, she longed for (渴望) siblings. When she gave birth to three daughters, the fulfillment (实现) of her dream had only just begun. She had given each of us a gift and she wanted to make sure we did not take that gift for granted. She would frequently tell us how lucky we were. But there were other, more subtle (难以察觉的) ways that she encouraged us to grow closer. She never showed favoritism to one daughter over the other, as not to cause jealousy or bitterness between sisters. She constantly took us places together—skating, shopping and swimming, so that we developed common interests. And when we were teenagers, Mom always punished us equally, giving us yet another bonding (密切相连) experience.

We didn’t always get along beautifully and fought just like any other siblings. But somewhere in between Mom’s lectures, the family vacations and the shared memories, we realized that our mother was right. Today I share things with my sisters that I do with no one else. My sister Cindy and I ran the New York City Marathon together, side by side, even holding hands when we crossed the finish line. When my sister Karen got married, I was her maid of honor(伴娘). Cindy and I traveled through Europe together and even shared an apartment for two years. The three of us trust each other with our greatest secrets.

It was twenty-three years ago that my mother first asked me who my two best friends were. Today she doesn’t have to. She already knows.
