Louis always interrupts! All of his thoughts are very important to him, and when he has something to say, his words rumble and grumble in his tummy, they wiggle and jiggle on his tongue and then they push on his teeth, right before he erupts (or interrupts). His mouth is a volcano! But when others begin to interrupt Louis, he learns how to respectfully wait for his turn to talk. PreK-Grade 3. Paperback.
