Lucky Day

Woke up at 10pm and get my ready in a rush to library. It is a routine that I will go to my friend's room before I go back to my room, all my meals are taken at my friend's house. When I want to go back, I can't find my key. OMG, a replacement key will cost me £30.
So I walked back to my room and found that the key is on the keyhole. When I opened the door, all my belongings are still here, especially my I-Book.
