Friendship--and trains!--take center stage in this gentle, inviting story about paying attention to other people's feelings.Two boys' fun train-track-building project takes a turn when one of the boys obliviously insists on only doing things his way. Their disagreement spells disaster for the train and the friendship, until a kind teacher steps in and explains how to tell when a friend is feeling happy, frustrated, or angry. . . and how to ask for a do-over.Compromising and paying attention to how other people are feeling can be hard for any kid, but especially for kids on the autism spectrum. Samatha Cotterill's third book in the Little Senses series provides gentle guidance along with adorable illustrations to help every kid navigate the twists and turns of friendship and working together.
