It was a sunny afternoon when I was walking home and spotted a key on the sidewalk. The key was plain silver and I picked it up. There was a note, and it said that this key can open any door but one. When I got home, instead of using the house key to open the front door, I used the key I found on the side walk. It worked! As I closed the door, I ran upstairs to keep put the key in a secret place because my sister Ella is very good at finding things. There is only one place she would not find my key, which is under my bed. So, I grabbed tape and taped the key under my bed. “That should do it!” I said. Just then I heard something like two pans clashing together from under my bed. and If the key is too heavy for the tape, then I have to put the key in my pillow case. When I tried my second idea, it worked and the key would be safe until Ella finds it in my pillow case. It was fine until , when I did not see Ella go into the room and find out that I hid the key in my pillow case. She asked me what was going on, and I told her the story of finding the key. and I told her it does work. She wanted to see if it really works, so I tested it the a second time, and it still worked! So, Ella told me to try the office because we always wanted a key to open the office door. and When we tried the key, it disappeared and left us a note. and It said, “If you try a door that does not work for the key, you will lose the key.” “Well Ella, I guess we lost the key,” I said upset.
