I am a good boy

Yesterday morning, I incidentally found a SIM password card in a book on logistics. When I went back dorm, I added it as my friend by Fection. Last night, we started our conversation. She told me that she is a female. OK. I asked whether she would like to get the card back. She said definitely yes. I asked whether she was a sophomore or junior student. She said neither. She is actually a postgraduate of second grade in Logistics. Oh! To my surprised! And I said I would leave the supervisor of her block next day. She told me her name and which block she lives. I said that my finding her card was a luck. However, she said that most of the people would find that card, but seldom would return it to its owner. And she said I did a good job.
I always do this thing. I always return what I pick up to its owner, though others will think that I am a fool.
This morning, I planned to study in the library again and returned the book I borrowed just one week ago, because I don't have enough time to read any more. Whereas, the library is closing today for the job fair. So, today, our campus is full of people. Some are coming to take part in the Public Servant Examination, while some are coming to the job fair. Everyone who decides to study was forced to the 24 hour self-study area, but obviously the seats there are totally not enough. And I dislike the air there. It's so dirty and frustrating! So after the morning reading, I quitted and back dorm. In the dorm, I sat down and started reading the book I planned to return this morning. The name of this book is 'Why the lucky guys are always lucky, while the unlucky guys are always unlucky'. I finished it in one breath! And I marked down what I need! It's a great book! Thank god, I didn't return it! Though I damned the school's closing library policy, I have to thank it!
Now I have to make better decision!
