Shana gripped her lock in her hand trying not to drop it,the last thing she wanted to do was lose it.She walked down the stairs and started to think about somewhere she could lock without getting in trouble.She walked up to one of the empty classroom doors,She peered inside just to check there was no-one inside.She didn't want to lock anyone in.She closed the door and put on her lock.Come on ClockWork Lock this door.Shana was going mad she was talking to a lock.Weird.She tried to open the door just to check it was locked.Shana got her wand ready and pointed it directly at the the lock Alohomora! She exclaimed trying not to disturb anyone.The lock opened.Good work Clockwork!She pulled the lock off the door and put her wand away.She opened the classroom door and left it just how it was when she started and began to walk back up the stairs.
