I don't know. I like the story, and will definitely share it with my kids. I may even recommend this to parents looking for a silly story on manners. But I'm just not sure I'm brave enough to knowingly bring a book into the school library that talks about but shows nose picking, burping, tooting, you name it. That said, it is a very fun story about manners. Pete the monkey learns very quickly why his parents ask him to say his pleases, thank yous and excuse mes!
