家   徽

余  华

       ①国有国徽，校有校徽，厂有厂徽，奇怪吗？我家竟有家徽。我们家的家徽是一条鱼，一条画在门板上的鱼。那条鱼画得很笨拙，线条零乱而粗糙，只能让人意会到是条鱼而已。但它却有不寻常的来历。

       ②祖父在世时，膝下有父亲他们弟兄四个，个个都是身高马大的男子汉，民国初年，战乱频繁，家庭仗着几个男人下死力气勉强维持着温饱。

       ③一天夜半，父亲起来小解，发现一条人影窜进了厨房，他便喊叫起来，同时马上守住厨房门口。不一会儿，父亲弟兄几个都起来了，他们点着灯，拿来大木棒子和斧头，仔细地搜索着厨房的每一个角落。厨房的旮旮旯旯都搜遍了，却没发现人。父亲弟兄几个说父亲定是半夜眼花，父亲赌咒发誓说肯定有人，还在争辩时祖父来了，祖父让儿子们都去睡觉。等他们兄弟走了后，祖父走到水缸边，敲敲盖子，说：“你不用躲了，出来吧。”只见这时水缸里水淋淋地站起一个人来，这人一手擎着水缸木盖，浑身颤抖，面无人色，另一只手里，还攥着一布袋大米哩。

       ④祖父望着窃贼，叹口气说：“算了，你走吧，要是让我的儿子们看见了，你今天非得残废不可。”

       ⑤贼傻望着祖父，他不敢相信祖父就这样轻易地让他走，但祖父分明是平静地挥了挥手，贼便从水缸里爬出来。祖父又把那水淋淋的米袋子交给他说：“带上它吧，它可帮你家度几天日子。”贼要说什么，却眼眶红了，低着头，提着米袋子往外走，走到门口，“慢着，”祖父又叫住他，塞给他一串铜钱：“你拿这些钱去做个小生意，再也不要干这伤天害理的勾当了。”

       ⑥贼“扑通”一声跪在地上，给祖父磕了几个响头，便走了。

       ⑦不知过了多久，一天清晨，祖父一开门，便在门环上发现了一条两斤多的鲜鱼。祖父先是感到奇怪，但马上他醒悟到是那贼送来的，那人大约是做了贩鱼的生意。

       ⑧自此以后，我家门环经常出现鲜鱼，家里便经常可以改善生活。父亲他们感到奇怪，祖父便舒缓地向父亲弟兄们讲起鱼的来历。

       ⑨大约吃了几十条鱼后，祖父感到不安，说人家是小本经营，别吃垮了人家。于是连着几天半夜候着，一直熬了三个夜，终于让祖父遇见了那送鱼人。谁知不是那个贼，却是一个年轻渔人。这渔人是那贼的儿子，贼在临终前嘱咐他要坚持送鱼到我家来。祖父和父亲他们听着连连点头。为了不违亡人遗愿，祖父拿过一把刀子，让年轻人在我家门上刻一条鱼，并说从此不许他再送鱼，就用刻下的鱼替代好了。祖父同时叮嘱父亲弟兄们要保管好这条“鱼”，牢记这件事。

       ⑩于是，我们家按照祖父的意思，每次做屋或换门时，都保留这鱼的图案。它，自然而然地成了我家的家徽。
