Thank you very much to the kind librarian! When she found me totally perplexed as to how I’d gotten a fine and why, she waived it for me, with only a gentle warning not to do it again. Its nice to see people who are willing to admit that mistakes, whether on my part or the library computer’s, can happen.
Also thank you to the girl who, upon hearing I needed a plastic bag for something, promptly directed me to go to her locker, tip out the plastic bag she had in there, and take it. It was a huge help, and her willingness to offer well beyond what’s expected was very inspiring.
