部落格又换IP了

标题只是标题
我已经荒废了这里很久了，以至于我发现服务器访问不了的时候已经过了一阵了
写部落格不是我擅长的，我更擅长一句话扯淡，于是我更多的在开心和Twitter

最近开心出了个超级大亨的游戏，让我想起了大一还是大二的暑假在宿舍玩北京浮生记的日子，每天在那卖盗版光盘和上海小宝贝
这样的日子就这么一去不复返了

以前总是感叹岁月如梭，这两年却觉得时间过得好慢
可能是因为总在折腾，比如换了两次工作，搬了三次家之类的
现在我又可耻的厌倦了工作了，想想也挺扯淡的，就在前一阵还每天跟玩命似的
估计是大姨妈又来了，厌倦工作又不得不工作，是我等俗人的痛苦

好的事情也是有的，昨天我终于考完了驾照，在09年结束之前搞定了这个破事
今天又跟同事扯淡，买车这个事情比起买房来说靠谱多了，至少是靠自己努力能达到的目标

最后让我可耻的YY一下年终奖吧，我已经三年没见过丫了
今年会有例外吗？
