You're supposed to check out a book?

Jordan’s first trip to the school library was great. He was able to see all of the wonderful books at his disposal and learned the process of checking out a book. When Jordan got home from school that day, I expected to find a library book in his backpack. I looked through every pocket (my there are a lot) to no avail. I asked Jordan where his book was. He said “Mom, the librarian said the books have to be back at a certain time and I was worried I would forget it”. He's such a conscientious little boy. So I reassured him that I would help him remember to take his book back on time. Hopefully next library day I will find a book in his backpack.
