Being safe around things with wheels

My mom sent Natalie a book about being safe around things with wheels---buses, bikes, roller skates, cars, etc. Very informative and a current favorite (after Alice the Fairy by David Shannon). Anyway, we were reading this book together and she said "Look me! I getting on the bus wear yellow backback." Then she said "Look, there's you! Pushing baby sister!" (We're working on that...) A page later, "Look, there's daddy on motorcyle!" It's actually us, too.
Obviously a lot of good all the information about what to do, or not do, did. Either that or it just didn't stick, because we found her doing this last night!
