Suppose You Meet a Dinosaur by Judy Sierra (2016)
A little girl is shopping in a grocery store when—surprise!—she meets a dinosaur. Don't worry. The dinosaur is very friendly. She's polite, too. In this funny story, told in lilting read-aloud rhyme, the girl has numerous opportunities to be helpful to the clumsy shopping dino and demonstrate when to say "thank you," "excuse me," "I'm sorry," "You're welcome," and other niceties of life. Tim Bowers's whimsical illustrations bring an extra dimension of fun to Judy Sierra's hilarious picture book fantasy. Altogether, Suppose You Meet a Dinosaur is an entertaining and painless way to show kids why basic manners are a good thing to have.
