    Most teens can't wait to learn to drive. Not so with me. Driving made me nervous. I didn't get a license until I turned 24 years old. As a result, when I first married, we only had one car and car pooled to work. My husband's hours were different from mine by one hour. I worked earlier. So he dropped me off and went to the diner to drink coffee until work time.

    Then, in the afternoons, I leisurely walked the three miles to his work place where I waited in his car, reading a book.

    One day while waiting for him, I noticed the most beautiful Cadillac pull in the lot. It was powder blue and sleek looking. The kind of car you dream about. I was busily admiring the car, when I noticed the driver. Honestly, she was probably the prettiest woman I had ever seen off the movie screen.

    She pulled into the spot beside our car and it was all I could do not to stare. There was a striking resemblance to Liz Taylor. Jet black hair and alabaster skin. Our eyes made contact and she smiled at me. Her eyes were as blue as the sea, and teeth like an even row of pearls. She was wearing a light blue shirt that just matched her car. Peeking through her long, softly curled hair I could see gold hoop earrings. They had to be gold to shine like that. A couple of minutes later, a nice looking man came out of the building, entered her car, leaned over and kissed her and she drove away.

    Sitting there in my jeans, shirt and hair in a pony tail, I wanted to cry. How could some people have it all?

    Maybe I would have forgotten about her, but the following week, I saw her again. Then it became almost routine to see her about once a week. She seemed friendly and always waved, flashing a big smile. My envy lingered long after she drove away.

    Many nights when sleep evaded me, I would think about the beautiful lady. I wondered if she and her husband ate out, and where they dined, and what she was wearing. I wanted her to get out of the car and let me see her full length. Did she wear really high heeled shoes and pants, or a skirt.

    I would get my answers in a couple of weeks.

    Sitting in our usual parking lot, I was holding my book, watching her over the top of it. She was waiting and when her husband came to the car, she called to him. They spoke a few words and he opened the car door for her to step out. He took her arm and helped her out of the car. I could see very well as she moved to get out. She was wearing a skirt.

    She haltingly walked around to the passenger side very slowly, leaning on a walking cane. Sitting sideways in the car, she lifted one leg with her hands and then the other one. The beautiful lady had a prosthesis on the left leg and a brace on the right leg. I couldn't watch them drive away as the tears were blinding me. For weeks I had envied this woman and her way of life, while I had been able to walk three miles to our car!

    When my husband arrived and found me crying, he immediately asked what was wrong. Through my tears, I told him about the beautiful lady. He said he knew her husband and also knew the story. The beautiful lady and her parents were in a car that either stalled or got caught on the railroad tracks and was hit by a train. Both parents were killed and she was severely injured. She was only 12 years old. The railroad made a large settlement with her because the crossing had no signals. He explained her car was specially built for her needs as well as the home.

    I prayed for forgiveness all the way home. The lady I thought had everything I didn't. I realized how lucky I was to have my parents, the ability to walk, run or dance through life and many wonderful things money can't buy. I would not have traded places with the beautiful lady for anything.

    When you meet a person who seems to be much better off than you, don't be fooled.

刘文典:世上已无真狂徒

徐百柯

    2005年岁末,红学界颇不安宁,于是遥想当年,西南联大教授刘文典这样讲《红楼梦》:其时天已近晚,讲台上燃起烛光。不久,刘文典身着长衫,缓步走上讲台,坐定。一位女生站在桌边用热水瓶为他斟茶。先生从容饮尽一盏茶后,霍然站起,有板有眼地念出开场白“宁﹣吃﹣仙桃﹣一口,不﹣吃﹣烂杏﹣满筐!仙桃只要一口就行了啊……我讲《红楼梦》嘛,凡是别人说过的,我都不讲;凡是我讲的,别人都没有说过!今天给你们讲四个字就够了。”于是他拿起笔,转身在旁边架着的小黑板上写下“蓼汀花溆”四个大字。这次讲座原定在一间小教室开讲,后因听者甚众,改为大教室,还是容不下,只好改在联大教室区的广场上,学生席地而坐,洗耳恭听刘教授高论。

    刘氏在西南联大开《文选》课,不拘常规,常常乘兴随意,别开生面。上课前,先由校役提一壶茶,外带一根两尺来长的竹制旱烟袋,讲到得意处,就一边吸着旱烟,一边解说文章精义,下课铃响也不理会。有一次,他却只上了半小时的课,就忽然宣布说,今天提前下课,改在下星期三晚饭后七时半继续上课。原来,那天是阴历正月十五,他要在月光下讲《月赋》一篇。有学生追忆:届时,在校园里月光下摆下一圈座位,他老人家坐在中间,当着一轮皓月大讲其《月赋》,“俨如《世说新语》中的魏晋人物”。

    刘文典讲课时,同样是守旧派人物的吴宓也会前去听讲,而且总是坐在最后一排。刘教授闭目讲课,每讲到得意处,便抬头张目向后排望,然后问道“雨僧(是宓的字)兄以为如何?”每当这时,吴教授照例起立,恭恭敬敬地一面点头一面回答:“高见甚是,高见甚是。”两位名教授一问一答之状,惹得全场为之暗笑。

    一日,日机空袭,警报响起,联大的教授和学生四下散开躲避。刘文典跑到中途,忽然想起他“十二万分”佩服的陈寅恪身体羸弱且目力衰竭,于是便率几个学生折回来搀扶着陈往城外跑去。他强撑着不让学生扶他,大声叫嚷着:“保存国粹要紧!保存国粹要紧!”让学生们搀着陈先走。这时,只见他平素藐视的新文学作家沈从文也在人流中,便顾不得自己气喘如牛,转身呵斥道:“你跑什么跑?我刘某人是在替庄子跑,我要死了,就没人讲《庄子》了!你替谁跑?”

    刘文典多年潜心研究庄子,出版了十卷本《庄子补正》,陈寅恪为之作序,推崇备至。曾有人向刘氏问起古今治庄子者的得失,他大发感慨,口出狂言道:“在中国真正懂得《庄子》的,只有两个人。一个是庄周,还有一个就是刘某人。”狂则狂矣,当下不少见,但其背后那股子傲骨嶙峋的气度,却是今人学不来的。

    1928年,蒋介石掌握大权不久,想提高自己的声望,曾多次表示要到刘文典主持校务的安徽大学去视察,但刘拒绝其到校“训话”。后来,蒋虽如愿以偿,可是在他视察时,校园到处冷冷清清,并没有他所希望的那种隆重而热烈的欢迎场面。一切皆因为刘文典冷冷掷出的一句话:“大学不是衙门。”

    后来安徽发生学潮,蒋介石召见刘文典。之前刘氏曾有豪言“我刘叔雅(“叔雅”为刘文典的字)并非贩夫走卒,即是高官也不应对我呼之而来,挥手而去。蒋介石一介武夫耳,其奈我何!”见面时,刘称蒋为“先生”而不称“主席”,蒋很是不满。进而两人冲突升级,刘文典指着蒋介石说:“你就是军阀!”蒋介石则以“治学不严”为由,将刘当场羁押,说要枪毙。后来多亏蔡元培等人说情,关了一个月才获释。

    后人赞曰:“好个刘文典,名士风流,还是狷介狂人?我不知道,我能知道的是,今天,这样的知识分子已无处寻觅,所谓‘风流总被雨打风吹去’。”
