我不能忘記她。我真的
不能忘記她•不是因為我嘗
試了多次都失敗，而是我本
來不想忘記她·我和她過去
的一切，還歷歷在目，好像
發生在昨天似的。每次遇到
有關愛、生命或快樂等事物
時，我便不禁埋沒在一股洶
湧的回憶洪流與。這洪流，
找不知是從那裹開始，也不
知它會在何處停止，祇是永
遠，永遠的滾滾地流。
我是三年前在一個偶然的場
認識她的。事實上也不特別的，祇是我對她的印象
深RlJ了。我望她第一眼時，我便深深的被吸引了。
心而論，她不算太美，我曾見過比她美麗得多的少
，但不知怎的，我毫不猶豫地在心中對自己說：
了，這就是了·從那時開始·別的女子已失去了
引我的力量。當我坐在她的對面時，我真的目不轉
地看著她，我自己一點也不感覺到這是多慶的失態
呢。尤令我迷醉的是她的笑容·她笑起來是那樣甜悅
可愛，毫不讓人有反抗的餘地；又是來得那麼的自然
，半點也沒有矯飾的份兒。在我的眼底中，她還是一
個純潔率直的女孩子，我真的想從她身上，找尋出過
去年青的我。她的一舉一動，都足以使我回憶我以前
的一切。很奇怪。我平日應付少女的社交手腕，都不

分的勇氣，和在心中默念了多次才敢放肌說出來，但
說時又常常口吃吃似的，惹得她屢次怡然而笑，而我
，則滿面通紅。
愛，往往是從一點小小的火星，尋到合適的燃料
後，而慢慢燃燒起來的。根本上，愛就是生命的火花
；畢竟也是生命所不能缺少的原動力·我倆的愛，不
久已到了不能分開的地步。
不幸，人有悲歡離合，月有陰晴圓缺，上天
竟然嫉妒我們，死神的手把她從我的懷中搶走了。她
含笑而逝的那一剎那。我真的不敢再復回想。當時，
我曾悲痛得不欲倫生，哭泣不知凡幾。正是春蠶到
死絲方盡，蠟炬成灰淚始乾。然而，冗長的時問，
漸漸沖淡了我心中的創傷。
至今，兩年多了。我倆所留下在公園野郊的足跡
可能已被擦抹無遺，但她的倩影·甚至她的一切。卻
永不能從我的腦海中洗去。平日事務繁忙，那就沒有
怎樣，但當我獨自靜靜的坐著閒思，或在舊地重遊時
，她的笑容，便再次呈現出來。
最近，我竟埋頭於酒杯中，可能在酒醉時·迷矇
中，能重返舊夢，我的摯友文曾多次苦勸我自愛健康
，努力戒除這惡習，但我怎能怪他，他還祇是一個不
知天高地厚的小伙子呢．近日，對狂歡玩樂甚惑興趣
，每每不盡興不歸，藉以麻醉自己的思想，暫時拋開
心中的憂鬱，可惜回到家中時，無形的空虛，又再次
佔有我的心靈了。
案頭上相架中的少女，就是日夕不能忘懷的她。
媽時常罵我為何痴痴的凝望看而至寢食不思。唉！她
又怎知失去了的已不能再彌補了，又有誰能了解我的
心音）呢。她現在在何處？快樂不？她知不知這世界上
還有一個痴心人想念著她呢？她知不知道因為她離開
了我，我已喪失了生命的活力呢？昨日的歡樂的果子
，已成為今日的苦惱；明日生涯，何去何從呢？這一
切的一切，不斷在我的腦海中環繞著。
現時，在說不出的苦悶中，唯一的希望就是忘卻
過去的事物，拋棄現在的自己，而再次建立自己未來
新的世界，但是·。這一段遙遠的愛，又要到何時何日
才得以補償呢？兩條不同方向的線，
交叉於一點；
是快樂與快樂的起點，
點是沒有長潤，
沒有時分，
只在心靈深處，;
隨著命運的軌跡，
兩線各自向前·
是痛苦與痛苦的起點；
帶著似甜又酸的回憶，
負著懊悔的重袒，
直至永遠。
也許，線要不是直的，
始終，還有再交叉的一點髡
