Haunted library

Have you experienced something you couldn’t explain? Do you believe in ghosts? I don’t, not really, but still…

The floor is creaking slightly. I look around to see if someone is behind me, but I can’t see anyone. Even though I’m used to it by now, I stand up and look around in the empty library. Yes it’s empty despite the fact that I can hear the faint sound of footsteps. …or am I only imagining things?

Could someone be hiding behind one of the bookshelves? I shrug and decide to go back to what I was doing. It’s one of the calmer days.
Knowing that there are no such things as ghosts, I still check to position of the rocking chair when I come to work and when I’m leaving. Today is no different, it’s moved again, not much, only enough for me to notice. Who’s been using it? No one knows.

The presence, if there’s one, isn’t threatening or scary. We’re sharing the library and if he, I get the feeling it’s a he, isn’t complaining, so why should I?
