Brief scene or flash fiction? Some jobs are best done by those that love the night.
"Oh, Hello Mr. Kramer. I wasn't expecting you. Is something wrong?" Theodore Kazcmarek had been working as the night librarian for as long as anyone can remember and almost never had a head librarian stop by.
"No, I was working on the budget and realized that I had left some papers here. You know it has been ages since I was here this late. It's pretty quiet."
"Oh yes, Sir, just me, a few night owls and students burning both sides of the candle."
"And the homeless." The library was a place for them when it got too cold.
"Yes, Sir. But I know the regulars and we have an agreement. If they do not disturb anyone and clean up after themselves, they're welcome. I've rarely had a problem."
"Speaking of which, how long have you been here? It seems like forever."
"Oh, yes, sir. I can hardly remember when I wasn't the night librarian."
"And you never wanted to work the days?"
"No, it's quiet and lets me read. After all, I have all these books to go through."
"And your family doesn't mind?"
"No, sir. My wife died very long ago and we never had children."
"As long as your happy, I guess. No one else wants it. Well, let me get those papers or my wife will give me hell. Good night, Teddy."
"Good Night, Sir."
Seeing Kramer go get the papers and leave, Theodore had to think back. When was the last time he had not been the night librarian? It must have been Alexandria, before the big fire. Thank Amon that one of his priestesses was there to save his life. Had she not initiated him he would not have survived his injuries. She had been lovely, too bad that none of the followers of Amon can have children. After all, the undead are the undead.
