I entered the library and put my things in order, as it was still too early for people to arrive. I decided to clean it because it was likely that the books were full of dust, and that would give a bad reference of me as the owner of the establishment. I turned on the lights and the entrance sensor to hear when someone entered. In case I wasn't at my desk.
I fetched a duster, took a cloth and a liquid cleaner, started on the first floor, and it didn't take long to finish it. I did my best to avoid taking the books and stay reading. I grabbed my cleaning tools and went down to the first floor. Most of the shelves were high, but somehow I managed to get the dust off them.
I was in the comics and animated books section. It was at the back of the library, and there was a huge bookcase. I tied my hair in a ponytail and went up a metal ladder to climb to the top. I avoided looking down because I might fall. I was about to finish cleaning when I heard the sensor. Someone had entered.
