一杯水的温暖

王生文

    这是一天里最热的时段。

    毒辣的日头悬在半空里,炙烤着大院里的一草一花,水泥路白亮亮的,反射着刺眼的光,没有一丝风,没有一个人走动。整个院子像中暑了,蔫头耷脑地躺在烈日下。

    谁也没有想到,一辆运水的人力三轮车碾压着自身的影子,踏进院里来了。三轮车摇摇晃晃、吱吱呀呀地行进着,在宿舍楼前停下了。

    车上下来一位中年人,淋漓的汗水漫流在黝黑的脸上,浸湿了上身那件灰色的衬褂。他扯起搭在肩上的毛巾,囫囵擦了一把汗,便从车袋里摸出一个装饮用水的瓶子,摇了摇是空的,就又放回去了。水没喝上,中年人有点失望,但也就是一瞬间,他抬起头,眯着眼望了望,迅即从车上搬起一桶水,扛上肩,往宿舍楼里走去。

    原来,他是来给住在楼里的人家送水的。

    攀上,跨下,中年人搬着一桶又一桶的水往楼里送。几趟下来,他想喝杯水的愿望越来越强烈,可是那些人家都只是从透着冷气的门缝里塞给他五元钱,就让他把水放下了,他连讨杯水的机会都寻不到。总算只剩下一桶水了,并且还是二楼的,他算计着送完这桶水踏着空车回去,顶多半个小时就可以喝上水了。一想到马上有水喝,脚下又有劲了。

    门铃一响,不想这回门全打开了,是一位大妈,看见中年人连声叫道:“哎哟,看把你热的,快进屋来歇歇!”

    中年人放下水,看了看自己的模样,不好意思往屋里走,大妈见状,一把把他拉了进来,光洁的木质地砖上,留下了几个脏兮兮的脚印。

    大妈赶紧挪过一台风扇,凉爽的风顿时源源吹向中年人。

    “师傅,今天怎么是你送的水?”大妈问。

    “听说跑这路的顾不过来,我是他们临时叫来的。”

    “是的,都打电话要水,能顾得过来嘛。”大妈说这话时,已将一杯水递到了中年人面前,可是中年人没有接,问:“大妈,您家有一次性茶杯吗?”

    “……”大妈望着中年人,有些疑惑。

    “大妈,我患过肺结核。”

    一丝黯然从大妈的脸上掠过,随即淡然一笑,说:“不必顾忌,没事的,你快喝吧,是温水。”

    中年人接过水,脖子一仰,干了。一杯温水下肚,他感觉舒坦多了,就返身从门口把水提进来,拆了封,装到饮水机上。大妈也就让中年人帮着装水,等他装好了水,掏出五元钱来给他。中年人收了钱正要离去,大妈又叫住了他,让他等一等。

    大妈去房里取回几盒药来,对中年人说:“这是进口药,专治那病的,你拿去问问医生,要是行就服了吧。记着,那病要根治,一旦复发就有些难了……”

    大妈说着说着,声音有些异样,中年人不解地望着大妈,大妈将药塞进他的手里,又说:“拿着吧,我女儿从国外寄来的,都是上好的药,只是……我家老头……他自个耽误了……”

    中年人明白了,心里难过起来,两眼一润,想说些什么,可一时又不知从哪里说起,像个孩子似的站在大妈的面前,好一会才说:“大妈,您老人家今后要是有力气活,就打我电话!”

    踏车回去的时候,中年人感觉腿脚都是劲,日头好像减了几分威力……

    My mom takes pride in the fact that I was talking in three and four word sentences before I was ten months old. Some say it's a gift while others simply think I talk too much.

    As my thirties came to a close, I found myself reflecting on my life. I'm very happy and have no significant regrets. However, when I looked back on those times of difficulty, I saw a clear common denominator(特征); I didn't seem to know when to stop talking. Whether it was hurting someone's feelings, or having carelessly told a secret, the incident could have been avoided had I closed my mouth sooner. So I decided to practice the power of quiet.

    To take this step, I needed to understand how people could sit comfortably in a group and not talk. Why does my husband feel completely content to say nothing in a conversation? He's highly intelligent and has wonderful opinions but he'll sit quietly and just listen. Even when he's asked a pointed question, he'll answer with few words while still communicating effectively. What a talent!

    Can you imagine being happy just listening? In surveying those I know who talk less than I do, I got two answers—they either didn't feel confident enough to speak up, or they just didn't feel the need to participate in the conversation. Of course there were other reasons for not talking, but these were the two most popular answers.

    The first one didn't work for me. I'm just fine letting people know what I think about them, and hopefully it will make the conversation much more interesting. The second one didn't work either. I do feel the need to participate. I feel it physically like an electrical pulse through my body; sometimes it's so strong that it causes me to behave badly in the form of interrupting or speaking in an unusually loud voice. I had to look further.

    An interesting thing happened on this journey to the power of quiet. During my weekly yoga class, it came to me like an answer so clear that the words rang in my head like soft, heavenly bells.

    I talked too much so people would know I cared about them. It was my way of taking care of those I love. I decided before my fortieth birthday, that from that day forward, those around me would know I loved them, and cared what they thought and felt, but I was going to practice the power of quiet.

    As my forty-second birthday approaches, I can say that deciding to talk less has been more about focusing on quality rather than quantity. I've found that listening more shows those who I care about that I really do care how they feel. Now when I break in, it means more to them. Oh, sure, I still have my short periods of talking too much, but for the most part this has been one resolution that I can call a success.
