我对着眼前这把锈迹斑斑的钥匙想了很久,终于想起来这应该是去年我租住过的玉泉小区10栋3单元502的门钥匙。我奇怪这把钥匙为什么还在抽屉里,因为记得搬走的时候,钥匙明明是还给房东了的。我决定去玉泉小区看看,去试试这把钥匙还能不能打开那扇门。也许房主早就换掉了锁芯,那也无所谓,我可以去看看那里现在有没有人住,或者是个什么样的人住在里面。等我换了两路公交车到达玉泉小区的时候,天已经完全黑下来。整 I looked in front of this rusty key think for a long time, and finally remembered that last year I should rent Yuquan district 10 3 502 unit door keys. I wonder why this key is still in the drawer, because remember the key when moving back to the landlord obviously. I decided to look Yuquan district, to try this key can not open the door. Perhaps the owner has already replaced the cylinder, it does not matter, I can see where there is no one living, or what kind of people live inside. When I changed two bus arrived Yuquan district, the sky has been completely dark down. whole
