Mac and Cheese are the class guinea pigs, and Oliver is their biggest fan. So he watches them to learn how he can be a good friend. But while snuggling might be fine for guinea pigs, Oliver's classmates don't like him getting in their personal space bubbles. With the help of his teacher and classmates, Oliver learns that being a friend means respecting personal space.

“At a time when parents and teachers struggle to teach kids about how close is close—what is appropriate personal space—here comes Mac and Cheese to gently show the way. Jolene Gutiérrez’s text and Heather Bell’s illustrations provide a light-hearted story that demonstrates how kids live, think, and act. Sure, it’s needful teaching but it does so in a sweet and meaningful way.” —Avi, winner of the Newbery Medal and author of over 75 books
 
“Adorably illustrated and gently written, Mac and Cheese is a delight.” —Elana K. Arnold, award-winning author of A Boy Called Bat
