| 睇番自己之前既日記=.=
都唔記得自己曾經有過咁既諗法....不過幾得意
睇返之前.... 覺得自己唔得左
無左之前果個心.....
係時候搵返自己^^ 半年打一次XANGA.... 可能係真掛
我個人太懶喇.... 要成日打會覺得好煩=.=
所以大家唔好見怪 今日係LAB坐左半日....
都係做左C++ 其他野都好似無做過
人大左時間真係唔係好夠用 前幾日同唔知邊個講
人大左時間變得無咁見使
細個果陣時間係用黎睇卡通片 等睇卡通片同玩
(我同一般小朋友唔同....我係屋企係唔做功課的...直至中六七)
由其係等卡通播係最耐 而家眨下眼就過.....一日都做唔到D咩
可能係因為人大左會訓晏左
細個要6點幾起身
而家7點起係好難得既事 無聊住咁多先....唔係聽日又起唔到... |

| 好耐無打XANGA........大家唔好怪我........
今個SEM都幾忙.......同埋對部腦對得多真係會嘔....... 放假喇~~~頹完一個星期開始搵工~~~
但係要搵返電腦既工真係好難.......好多都要經驗....仲有好多我唔識既電腦知識....e.g. Linux
不過好在學校係placement~~雖然唔知請唔請我......但係總算有個希望~~
除左搵工我都開始增值自己.....開頭諗住學HTML.....
但係聽完偉健講又好似學Linux好D~~
雖然佢好似另有所謀.....但係我信佢唔會點我行條歪路~~~ ^^ 今晚去完街返黎終於學識左用終諯機開機,熄機,睇時間,日期,月歷,計數機,查d COMMOND點用~~~
都幾煩下~~但係又幾好玩^^
請大家都為我個暑假祈個禱^^ |
