Are "Friends" Paper?

Another late shift. After a busy day of parent-teacher interviews, I then got all the school book club books bagged up and ready to go home on Monday. It does my heart good to know there's a girl in our school who will cherish the book fifth row up, sixth from left. 

"Books are the quietest and most constant of friends; they are the most accessible and wisest of counselors, and the most patient of teachers."
