                                                                                                  丁立梅
       ①迷恋蔷薇,是从迷恋它的名字开始的。
       ②乡野里多花,从春到秋,烂漫地开。很多是没有名的,乡人们统称它们为野花。蔷薇却不同,它有很好听的名字,祖母叫它野蔷薇。野蔷薇呀,祖母瞟一眼花,语调轻轻柔柔。臂弯处挎着的篮子里,有青草绿意荡漾。
       ③野蔷薇一丛一丛,长在沟渠旁。花细白,极香,香里,又溢着甜。是蜂蜜的味道。茎却多刺,是不可侵犯的尖锐。人从它旁边过,极易被它的刺划伤肌肤。我却顾不得这些,常忍了被刺伤的痛,攀了花枝带回家,放到喝水的杯里养着。
       ④一屋的香铺开来,款款地。人在屋子里走,一呼一吸间,都缠绕了花香。年少的时光,就这样被浸得香香的。成年后,我偶在一行文字里,看到这样一句:“吸进的是鲜花,吐出的是芬芳。”心念一转,原来,一呼一吸是这么的好,活着是这么的好,我不由得想起遥远的野蔷薇,想念它们长在沟渠旁的模样。
       ⑤后来我读《红楼梦》,最不能忘一个片段,是一个叫龄官的丫头,于五月的蔷薇花架下,一遍一遍用金簪在地上划“蔷”字。在那里,爱情是一簇蔷薇花开,却藏了刺。但有谁会介意那些刺呢?血痕里,有向往的天长地久。想来世间的爱情,大抵都要如此披荆斩棘,甜蜜的花,是诱惑人心的猸。为了它,可以没有日月轮转,可以没有天地万物。就像那个龄官,雨淋透了纱衣也不自知。
       ⑥对龄官,我始终怀了怜惜。女孩过分的痴,一般难成善果。这是尘世的无情。然又有它的好,它是枝头一朵蔷薇,在风里兀自妖娆。滚滚红尘里,能有这般爱的执著,是幸运,它让人的心,在静夜里,会暖一下,再暖一下。
       ⑦唐人高骈有首写蔷薇的诗,我极喜欢。“绿树阴浓夏日长,楼台倒影入池塘。水晶帘动微风起,满架蔷薇一院香。”天热起来了,风吹帘动,一切昏昏欲睡,却有满架的蔷薇,独自欢笑。眉眼里,流转着无限风情。哪里经得起风吹啊?轻轻一流转,散开,是香。再轻轻一流转,散开,还是香。一院的香。
       ⑧我居住的小城,蔷薇花多。是午后时分,路上行人稀少,且都是懒懒的。蔷薇从一堵墙内探出身子来,柔软的枝条上,缀满一朵一朵细小的花,花粉红,细皮嫩肉的样子。此时此刻,花开着,太阳好着,人安康着,心里有安然的满足。
       ⑨美丽的女友,远在黑龙江,她喜欢画画,她画的画极漂亮。她在画里画蔷薇,却说,可惜,只见过照片上的蔷薇。
       ⑩忍不住笑。竟有这样的喜欢,不曾谋面却念念于心。我对她说,等我有空了,我会掐一朵蔷薇给你寄过去。

    Some people will do just about anything to save money. And I am one of them. Take my family's last vacation. It was my six-year-old son's winter break form school, and we were heading home from Fort Lauderdale after a week-long trip. The flight was overbooked, and Delta, the airline, offered us $400 per person in credits to give up our seats and leave the next day. I had meetings in New York, so I had to get back. But that didn't mean my husband and my son couldn't stay. I took my nine-month-old and took off for home.

    The next day, my husband and son were offered more credits to take an even later flight. Yes, I encouraged—okay, ordered—them to wait it out at the airport, to "earn" more Delta Dollars. Our total take: $1,600. Not bad, huh?

    Now some people may think I'm a bad mother and not such a great wife either. But as a big-time bargain hunter, I know the value of a dollar. And these days, a good deal is something few of us can afford to pass up.

    I've made a living looking for the best deals and exposing (揭露) the worst tricks. I have been the consumer reporter of NBC's Today show for over a decade. I have written a couple of books including one titled Tricks of the Trade: A Consumer Survival Guide. And I really do what I believe in.

    I tell you this because there is no shame in getting your money's worth. I'm also tightfisted when it comes to shoes, clothes for my children, and expensive restaurants. But I wouldn't hesitate to spend on a good haircut. It keeps its shape longer, and it's the first thing people notice. And I will also spend on a classic piece of furniture. Quality lasts.
