Last week, I had to woken up before I went to the class. I had to have breakfast at the canteen. When I finished, I was to drive to the classroom. Unexpected event happened, My Car key lost. I was found my key around the canteen. I didn't know how to do. I sat at the table waiting for me to eat. Suddenly someone came. Someone announced that "Whose is car key ".
I would have lost my key, If he didn't see this. I'm so glad this That would have returned the car keys. I should have thanked him for the car key.
If I kept my key carefully, I could not have found my car key at that time
