大碗和小碗

胡 军
①表哥六岁的时候，姑母因病去世，给姑父留下大笔债务。八岁那年，姑父再婚。继母来自市郊农村，给表哥带来了六岁的弟弟。
②弟弟娇惯不懂事。那年头，家里日子过得很紧。可弟弟老嫌母亲给自己盛的饭菜比哥哥的少，所以常常在饭桌上闹别扭。
③几次吵闹后，弟弟从碗柜里找了只敞口大碗，坚持要母亲用大碗给他盛饭菜，不然就不吃饭。继母心疼地望着瘦猴似的弟弟，答应了，不过开出条件：“哥哥也要换只碗。”第二天在饭桌上，继母将一只新碗递到他手里，笑着冲他眨眨眼说：“弟弟小，做哥哥的就让着他点儿。”弟弟见状，马上将新碗抢过去，和自己的大碗比，一看口径小不少，不吭声了，低头乖乖吃饭。
④虽然觉得继母待他不错，自己也该让着弟弟，表哥心里仍然有疙瘩，在继母心里，亲生的毕竟还是不一样。
⑤后来，继母去世。上个月，父亲也撒手而去。那天，表哥到父亲生前住的老房子里收拾，在一堆杂物里，居然看见了那两只他和弟弟儿时的专用碗。
⑥一个念头忽然从心头升起，表哥虽然觉得荒唐，还是按捺不住要试试。他用水把弟弟的大碗灌满，然后将大碗里的水朝自己的小碗里倒，结果，大碗的水倒光了，小碗还剩四分之一没满。表哥不信，把两只碗平放在桌面再比较，小碗接近直筒形，上下几乎一般大，大碗则口宽底窄，而且小碗比大碗高出一截。这就是两只碗的秘密，如此简单。表哥感到奇怪，自己怎么到．今天才发现。
⑦儿时一家四口围着方桌吃饭的情景又清晰呈现在眼前，继母给父亲盛好饭菜后，再给他和弟弟盛，兄弟俩每人的碗里都是满满的，然后才轮到她自己，末了常常是父亲看到剩下的饭菜少，又将自己的往继母碗里拨。记忆中的这一幕顿时变得好温馨，好动人。
⑧于是，表哥和弟弟约好，接下来的星期天，带上各自家人，还有那两只碗，到郊外给父母扫墓。
⑨世间有一种无私的爱，因其质朴，因其不事张扬，不求回报，有时即便被爱者也难以觉察，甚至产生误解。但是，爱毕竟是爱，终究有那么一天，这种爱，这种无私会被感觉，被认可，被传递，人的心灵也得以滋润、温暖和净化。

羧酸酸味的强度顺序是：甲酸＞丙酸＞乙酸＞丁酸。
