Hoodwinked

Yeah, I hate to admit, but she got me good. What she doesn't realize, is that I won't let it happen again.

Last Wednesday, I was at my desk talking on my cell, when one of the supervisors(not mine) approached me. I told my friend that I'd call her back.
So, MsAbsentMinded asks me if I would come to work an hour later Thursday and work until 8pm. My first answer was no, because I made a deal when I began working in this department. I work Sundays, so I never have to work a weeknight. Ms.A.M.(Absent Minded) said okay, but went on to whine, "But I don't know if NeverCome2Work will show up. She returns from LA in the morning.". The whole time, I'm looking at Ms.A.M.and thinking that isn't my problem.
Since I was looking at her with a strange look, she asked, "Do you have plans? If you say no, I'll just ask 1 of the pages to sit at the reference desk with me." After about 7 mintes, I finally agreed.
Thursday, NeverCome2Work was scheduled to arrive at 12:30pm. I decided that I would just tell her to work the last hour and go home early. About 1:20pm, I see NeverCome2Work walking up the stairs toward our floor. The only librarian on my floor who looks like me is going down the stairs. He stopped, said something to NeverCome2Work; she turned around and left.
I found out later that afternoon that MsA.M. told NeverCome2Work that she didn't have to show up.
My supervisor said,"You are so good, the favor will be returned to you.". My response, "Funny how MsA.M. waited until after you left for the day to talk about changing my schedule.
