发展快到让我觉得自己在退步了

身体被自己糟蹋的得了大病  真不知还得病多久 医生居然说最少还得半年

每天吃那么多药 没病也能吃出些病来

想想片子上已经空了的那半边肺  后怕..

本想着 在休息的这些日子 做很多事 可是 吃了药  人不得不睡觉

吃了睡  睡了吃

梦总是很多 可想想正事 一切还是迷茫

房价好像不怎么涨了 可是好像还是买不起啊

有同事最近要结婚了 恭喜 可惜我也去不了

没病的时候 经常幻想有 几个月 辞职出去 川藏  来一回间隔年

呵呵 ..现在终于有时间了 却哪也去不了  连门口的公园一口气都 逛不下来..   想想真可笑

苦笑..

建议用 Chrome  ,  Firefox 浏览   Chrome 的运行效率会高一些

第一视角游戏

来自很老的一个例子        源文件 z_mapping.fla

最近结婚的朋友特别多  有点小惆怅

不过想想 玩的很好的一个发小孩子都上小学了 既然这样自己也无所谓了

周末去周边的大学散散步  又回想自己的 大学时怎么过的  呵呵

想想如今有时加班忙的昏天暗地 衣服都抽不出时间来洗

所以羡慕啊 呵呵

不过看豆豆还是挺乐的
