The collection you'll receive when....

...your Nana used to teach Second Grade. Thank you, Nana!

P.S. Jack was asleep while we organized all the books. I predict by 7:01 tomorrow morning, 60% of the books will be on the floor again.

P.S.S. I panicked when typing the above-sentence. Which word is correct "Use" or "Used"? Ms. Second-Grade teacher, help please!?!?!
