她終於有勇氣重新開箱，拾出當年所封存的那些記憶。只不過那也是最後一次，那些記憶在開箱之後，不再散發香水的味道；所拾出的東西，也就直接進了垃圾袋。

她看著垃圾車的壓縮機輾壓過那些她曾經珍惜過的曾經，然後看著垃圾車駛離。「就這樣，」她想。

因為那一年某堂粗淺的人類學課程，讓她心生一計，開始買一個又一個的箱子，把那些碰觸不得的潰爛和難堪，給一一封存起來。離別的痛苦，伴隨著的是碰不得的屍體：生存與死亡的界限，生食與熟食，潔淨與塵垢。葬禮與守喪的時間延遞，是一種轉化的過程：當不潔的屍身再度化為了塵土，不可碰觸的終將化為了無所謂的──可以如清掃家門般將之一掃而出。

她花了整整一年的時間，把那些曾經有過的曾經給一一打包、整理、刷洗、更衣，她一邊整理一邊自言自語，哪些是她的初次、她的愚念、她的痴心、她的自甘墮落。來來往往這麼多年，她必須精心計算，購足相當數量的箱子、膠布、標籤紙，那些不可能再穿的衣服也得一一送洗、折疊、包裝。她編目，用圖書館員的耐心一一貼上標籤，空出架位，測量每件物品的大小──用了一半的香水瓶、一件毛衣、一本書、一張大頭照、一張小紙條、兩片CD、一盒太陽眼鏡…… 曾經她一度想將之一一整理販售，但是想到這世界之小，這些物品未來的主人將來說不定碰到原主，或者就只是那些人會在拍賣網站上看到。她雖然復仇心重，卻還是對散心大拍賣這種事有所保留。

全部封箱完的那一天，她完全崩潰，累倒在床上，高燒了整整兩天。

然後這一切都結束了。至少，暫時如此。

那幾年中，箱子就放在她的床下。她家人以為是學生時代的筆記書本，不曾多問。起先她還有睡在回憶上的感覺，之後她搬家、換工作，完完全全與箱子的世界分離了開來，也避開所有重新和那世界回復聯結的可能。不聯絡、不寫信、不和任何可能碰觸到箱子世界的人往來。稍微一點點可能觸及的預感（她這幾年因此嗅覺變得無比敏銳），就立刻送入隱形或擋駕名單。

只有在很後來，當她開始想要做更遠距離的移動時，才又突然想起那些箱子的存在。那些丟不掉搬不走的掛念，任何一個箱子都是一條連往過去的通道。那些被貼上封條的通道不會讓她陷落，她感到安全，然而她也不確定她是否哪天會有勇氣，重新開箱啟動這一切，再次於經驗的記憶中走一遭。

一直到了那一天。

她本來還想再拍張照片的。所謂符號的記憶，所謂的牌位：咒文或碑文，如一個指標般，指向那曾經存在的實體和全部。當一切身體都消逝，還有那符號可以喚起曾經存在的事實。所謂的記憶。然而那一天她發現了這記憶的弔詭：如同照片提醒了箱子的曾經存在，她似乎也可以將照片放置在她心中，用那照片的曾經存在，來指向那些指向了箱子曾經存在的照片。既然如此，拍照與否，又有什麼差別？

用刀片將膠布拆開，一一拾起那箱子中的物品時，她突然覺得，她已經和這些一點關係都沒有了──甚至不再是「距離已經很遙遠很遙遠」。距離：兩個實體間存在的空間關係。沒有關係：就連距離也不再存在的事實。沒有了距離也就不再感受到遙遠，那些如深淵般的通道裡傳來的微弱聲響也消失了。於是同樣也沒有了回頭：那稱作這一切起點的單一事件，已經消失在意識的地平面上。

她來到了經驗的新島嶼。

突然之間，那些放在她房間裡的一個個箱子，變成了外來的異物，路邊的灰塵。

開始丟棄那些箱子。不，這並不是否認。否認一件事物的前提是事物的存在。奇異的是她在丟棄之後，竟然得以開口說話。所有過去那些潰爛的難堪的不潔的，所有的恥辱和屈辱和自以為是，突然之間變成可以說的事情。那不只是因為她自己的經驗，或者，毋寧說，那已經不再只是經驗。個人的生命的經驗，隱沒銷融進入一個更廣闊無垠的核當中，那東西不需要任何被貼上封條的通道，也能夠被觸及到。

她自己的故事已經變得不是那麼無關緊要了，她想，隱沒進那無垠的才是。因為知道那無垠的存在，她突然覺得如同被釋放了一般。

第二天的清醒也因此變得如此值得期待了起來。她開始想獨自說說那隱沒帶下的無垠的事。

=head1 NAME

Text::Greeking::zh_TW - A module for generating meaningless Chinese text that creates the illusion of the finished document.

=head1 VERSION

This document describes Text::Greeking::zh_TW version 0.0.4

=head1 SYNOPSIS

  my $g = Text::Greeking::zh_TW->new;
  $g->paragraphs(3,15); # min of 1 paragraph and a max of 2
  $g->sentences(1,10);  # min of 2 sentences per paragraph and a max of 5
  $g->add_source($scalar); # use text yourself, not requisite
  print $g->generate;

=head1 DESCRIPTION

This module is for Chinese speakers to generate vary meanless Chinese text.

=head1 INTERFACE

=over

=item new()

Constructor.

=item paragraphs($min, $max)

Sets the minimum and maximum number of paragraphs to generate. Default is a minimum of 2 and a maximum of 8.

=item sentences($min, $max)

Sets the minimum and maximum number of sentences to generate per paragraph. Default is a minimum of 2 and a maximum of 8.

=item generate

Returns a body of random text generated from a randomly selected source using the minimum and maximum values set by paragraphs, sentences, and words minimum and maximum values. If generate is called without any sources a standard Lorem Ipsum block is used added to the sources and then used for processing the random text.

=item add_source($scalar)

Add text of yourself as corpus. Return instance itself, so we can add source serially.

    $g->add_source($source_one)->add_source($source_two);
