帽子

安勇

    早晨，送完女儿回到家里，她忽然觉得很不安。

    本来在十字路口，按她的意思还想往前送一段路，穿过那两条马路后再返回，可女儿刚好看见一个同学，就急三火四地摆摆手，和她说了声再见。等她再想说什么时，女儿已经拉着同学的手跑远了，留给她的只是一个小小的背影。

    丈夫还在床上睡着，几个房间里都流动着睡眠的味道。她用鼻子嗅了嗅，从空气里就闻到了属于女儿的味道。回忆起来，女儿的气味已经不知不觉地发生了些微妙的变化，从开始时淡淡的奶香，变成了如今活泼的青春气息。女儿呢，也从咿呀学语的婴儿，成了一名背着书包上学的小学生。想一想，这些仿佛都是一眨眼间的事情。

    她坐在沙发上发了一会儿呆，到底还是忍不住，走进大房间里，推醒了丈夫。丈夫揉着眼睛，嘟嘟囔囔地问出了啥大事，是天塌下来了，还是地陷下去了。她没有马上回答，努力让自己的心情平静下来后，才淡淡地说一句，我有点儿后悔，刚才不应该让孩子戴帽子。丈夫听了她的话，一下子从床上坐起来，伸出手摸她的额头，你没发烧吧，怎么头上一句脚上一句的说起了胡话。她打开丈夫的手，撇撇嘴，你才发烧呢，我说的是正经事。丈夫就不再理她，翻身下床，躲进了厕所里。她走到厕所门边，还想再说点什么时，话到嘴边又咽了下去，她有点隐隐的担忧，自己会不会一语成谶？

    在办公室里，整个上午，她的心里一直慌慌的，手上的工作也干得丢三落四，顾头不顾尾。眼前始终晃动着女儿戴着帽子的形象。她看见女儿背着书包、戴着帽子走在去学校的路上，眉飞色舞地和同学谈论着昨晚的综艺节目。两个孩子还因为喜欢的对象不同，发生了一点小小的争执。然后，她就看见女儿准备要过马路……想到这里，她就赶忙闭上眼睛，再也不敢想下去。

    到中午的时候，她的心更加慌乱起来。她和丈夫午休的时间都不长，女儿也不回家吃饭。每次早晨送女儿时，在路上她都会叮嘱几遍，中午别忘了给妈妈打个电话。她看看表，女儿放学的时间已经到了，但手机却静悄悄的，毫无反应。单位里的一个同事喊她去吃午饭，她嘴上答应一声，脚下却没动，还坐在办公桌前呆呆地看着手机出神。办公室里只剩下她一个人了，屋子里很静，她甚至能听到自己剧烈的心跳声。女儿下午上课的时间已经过了，但手机始终也没响起来。她突然想立刻就去女儿的学校看一看。就在她打算出门时，领导交给她一份报表，让她一定要在下班之前赶出来。

    她的业务水平在单位里是很棒的，如果在往常，这件事情她一个小时就能轻松地做好。但今天却不行，她发现自己每统计一次，得出的数字都不一样，最后，那些数字像一只只小虫子似的从纸上飞起来，让她眼花缭乱，无所适从，她想抓住任何一只，都很难。当终于把报表做好，交给领导时，她看见时钟马上就要指向女儿放学的时间了。她又一次看见女儿戴着帽子，心不在焉地从校门口走出来，一边挥手和同学说再见，一边穿过马路……她说声我得走了，去接女儿，就急匆匆地跑下办公楼，拦了辆出租车，向女儿的学校而去。

    女儿看见她从出租车里走出来时，表现得很惊讶，上上下下地看了她一遍。她也同样上上下下地看了女儿一遍。女儿说，今天这是怎么了，太阳从西边出来了，打车来接我？她的脸突然板起来，狠狠地说，中午为什么不给妈妈打电话？她的声音很大，旁边的几个家长和学生都扭过头来看。女儿觉得很委屈，眼泪一下子涌出来，围着眼圈儿转。人家忘了嘛，也不是故意的，再说，也不是第一次忘。

    她意识到自己有些过分，搂着女儿的肩膀说，好了，下次别再忘就行了。

    第二天早晨，她找出另一顶帽子，把昨天女儿戴的那顶帽子扔在了衣柜的角落里。女儿戴上帽子时有些不解，问她干吗换来换去的。她端详了女儿一会儿，淡淡地说，昨天那顶帽子，帽檐太长了，挡眼睛。

—I think you can do it _______.

    For most of my 20 years as a teacher, summer vacation was my time to relax. So why was I standing in the schoolyard of an unfamiliar school, wearing myself out for a summer teaching job? The extra paychecks were nice, but I lacked the energy of my younger colleagues. Like Stella. She was in her early twenties, and made keeping up with the kids look effortless. She reminded me of myself, back when I was a bright-eyed student teacher at Ramona Elementary…

    I'd never forget my first day. I was too full of energy. Nervous energy. My supervising teacher was watching, and I wanted to make a good impression. I asked my third graders to take out their crayons for the day's lesson. All of them obeyed. Except one. A girl with two long, dark braids(辫子). Everyone called her Estrellita, or “little star.” Why was she unprepared for class? I demanded to know.

    “My sister has my crayons,” she said.

    “You should each have your own crayons,” I told her. “That's no excuse.”

    “There are 10 children in my family,” Estrellita said quietly, her big brown eyes never leaving my face. “We have to take turns.”

    I was taken aback. I'd completely misjudged the situation. All day Estrellita's words played on my mind. The next morning I bought a pack of crayons to leave on Estrellita's desk. She was so happy! That experience taught me an important lesson. Every student had a unique set of challenges—it was my mission to help my students overcome them. That mission used to energize(激励 )me.

    Rest was almost over. Stella turned to me and we started chatting. “How long have you been teaching?” she asked. I told her I'd started twenty years before, at Ramona Elementary.

    “I went to school there twenty years ago!” Stella said. I looked at her again, this time really seeing her. Those big brown eyes. That long, dark hair...

    “Did you use to have two long braids?” I said. “We called you Estrellita… ”

    Stella shouted. “ You ! You gave me the crayons!”

She'd become a teacher. To help students like I did. Even doing something that small mattered.

    That summer, I threw myself into teaching with a renewed sense of purpose. Estrellita had taught me a lesson once again.
