Two days ago, I carried a few bags from my apartment to the car. Then I went back into the apartment building. I went up to the second floor very soon. I saw two boxes at the corner, but I remembered they weren’t there     . Maybe someone just put them there while I was     _ the bags.
I took out my     and tried to open the apartment door, but the key didn’t work. There were    keys on the desk when I got out of the apartment. I just took one of them and the other one was left there. Maybe I took the    key.     looked the same and that was quite possible.
When I was      again, a woman opened the door. She asked me if I needed any help. You could imagine how    _ I was. What was she doing in my apartment? Then I saw a new doorbell, and everything in the house looked different.
Then I realized that I had       into the wrong building. I said sorry to the      _  and left. Later I found that my apartment was the one in front of it.
