捡漏儿

许福元

    女友豆豆边往三轮排子车上啪啪扔纸箱子，边嘟着嘴假装生气，对男友亮亮说：“你是不是脑残呀？你卖自家的纸箱子还不够，还要收集别家的。也不够一壶醋钱，还不够我刷流量的呢。你要收破烂呀！”

    亮亮嘻嘻笑了：“我这是节约再生资源。收破烂咋啦？破烂里能捡漏儿！收破烂了！有破烂的卖喽！”

    亮亮蹬着三轮车吆喝，豆豆坐在他身后排子车纸板上，用温热的小手掌轻拍他后背。

    “收破烂的，这儿有几个纸箱子要不要？”说这话的是一个像退休职工又像离休干部，很干净很清爽的老人，拄杖立在一层单元门外，腿边三个纸箱子。

    亮亮捏闸跳下车，问：“多少钱？”

    “给三十吧。”老人用拐棍敲了敲纸箱子，听声音很瓷实。“刚才有个收破烂的开个三蹦子，我让他等一会儿。等我小孙子从电梯上搬下来时，他又开车突突冒黑烟走了。我这孙子呢，回去打游戏机去了。现在的孩子，不气你就不错了。这纸箱子里就是些旧书旧报纸。你收走，我到凉亭坐会儿。”

    亮亮把三个纸箱子搬上车，第三个纸箱子还挺沉。亮亮一边继续蹬车一边对豆豆说：“你还真跟小主似的，也不帮个忙，连车都不下。”

    “你还真能卖萌，好像你是大款似的，连房贷首付都交不起。也不讲个价，这三个破纸箱子，最多值十五块钱。”豆豆又呲儿他：“拐辅路，走辅路。”

    车子一颠一歪，豆豆随着纸箱子就溜了下来。摔疼了刚要发作，见纸箱子里掉出一板东西，金光一闪。豆豆眼光一亮，喊出了声：“钱！”

    是钱，还不止是一板。崭新的人民币，一百元一张。腰封很好，整齐硬实。一板一百张，一板一万。俩人看四周静悄悄，开始紧张地数钱，一板，两板，三板，四板，五板……好啊，整整五十板，五十万，五十万呐！

    天上掉下个大馅饼！

    这个大馅饼该怎么吃？

    亮亮挠着头问：“怎么办？”

    “还能怎么办？”豆豆话语里带着甜丝丝的味道，“贷款买房交首付当婚房。”

    “那不合适吧？这钱来得……”亮亮用手摸脖子。

    “是你偷的吗？”豆豆挺直脖子问。“不是。”“是你抢的吗？”“也不是。”

    “那不就得了么。”豆豆一副心安理得的样子，“你当了好几年志愿者，这也是上天对你的回报，你应该却之不恭。”

    亮亮一时无言以对。想了想，提出了这样一个问题：“这要是人家买房的钱呢？”

    “你这人可真是，你看这个老头的穿戴，像买两限房的工薪阶层吗？”

    “这钱要是老人的养老钱呢？”

    “嘁。”豆豆反问，“你看这老头的气质，像乡下老农存钱的土办法吗？”

    亮亮听了点点头。突然一激灵：“这个楼是银行的楼，这个老头要是个贪官……”

    豆豆一下子用小手捂住他的嘴，前后看了看，然后用手抚摸自己的胸口说：“吓死我了。”

    喘息一会儿，才定定地说：“《水浒》上有一句话，不义之财，取之何碍。”

    对。亮亮表示赞同，也动了心。

    可又一转念，很庄重地说：“这钱的来路弄不清楚，咱不能要。钱是老头的，还给老头；钱是贪官的，交给法律。”亮亮一指：“前边就是派出所……”

    豆豆有点气：“你去，我不去。”

    亮亮也气了，眉毛都立了起来：“我去，你也去。”

    豆豆顽皮地一笑：“你去咱俩就吹。”

    “吹就吹。”亮亮蹬车在前边飞。

    “等等我！”豆豆在后面飞似地追，“你想甩我，没门！”

    派出所新来的小警员觉得事态严重，报告了所长；所长觉得事件重要，报告了县局；县局觉得案情重大，派一名干练的警察协助调查。

    那个卖三个纸箱子的老头被“请”进派出所问询室，有笔录，有全程录像。

    纸箱子打开，齐刷刷露出五十板人民币，金光闪闪。老头见了，眼光那么一亮。所长审慎地问：“钱，五十万，是您的吗？”

    “是。”老头笑说：“这点钱不叫钱。”

    “你口气不小哇。”小警员冲口而出。

    老头用拐杖点点钞票：“是钱不假，钱是假钱。这是当年银行为训练职工手点钞票而特别印制的规范假钱，每张钞票都有浅浅印记。当年全行业点钞比赛，我得过全市第一名。你网上一搜就知道了。我没想卖，让我这小坏孙子搬错了。”

    噢，哇！原来如此。

    老头很感慨，又用拐杖敲敲那一排钞票：“潘家园的一个古董商看上了，愿出面值百分之三的价格收走。我没卖，想留个念想。现在好了，我送给你们这小两口，算你们捡个漏儿。”

    亮亮说：“谢谢您老人家。这个漏儿，我们不能捡。”

    “为什么？”

    “人生不是捡漏儿！”

The La Tomatina Festival

According to the magazine Fruit Today, Spanish people eat 17 kilos per person annually. They eat tomatoes every day and prepare them in a variety of ways, including fresh, crushed or stewed in a sauce. Tomato sauce (serve) on the side with fried eggs, chicken, and meat at most Spanish dinner tables.

Since one of the principal tomato-growing regions of Spain is the southeast, it seems appropriate that the famous tomato fight (take) place in Bunol, just west of the capital city of Valencia.

Interestingly, the La Tomatina festival (start) by accident. As history tells it there was a parade and festival in Bunol on the last Wednesday of August in 1945 when a fight (break) out between some young men. Taking advantage of a nearby fruit and vegetable vendor's stall, they threw tomatoes at each other. The police finally stopped the fight and those responsible ended up paying the stall owner.

Obviously planning ahead, the following year the young people brought tomatoes with them to the parade and started a tomato fight once again. Each year the fight continued until the early 1950s when it (stop) by order of the town council, but some local people insisted on creating a fight and (throw) in jail. Protests followed, and finally in 1957 the town council allowed the food fight to continue. In fact, since 1980 the city government (provide) tomatoes!

The celebration continues to take place on the last Wednesday in August in the plaza mayor of Bunol. The festival starts at 11 a.m. with the sound of a rocket being fired and ends one hour later. About 40, 000 people (expect) to participate in throwing over 100 tons of ripe tomatoes in the streets.

According to La Tomatina's official website, there are several simple rules that must (follow). Below are the official festival rules:

You must not bring bottles or other types of objects which could cause an accident.

You must not tear or throw t-shirts.

The tomatoes must (press) soft before throwing them to avoid hurting people.
