Now that his parents are separated, Ludo has two homes: one in the country with his mom, and the other in the city with his dad. The young boy doesn’t like leaving the countryside and his friends to go to his father’s apartment in the city, but he does find some entertainment in the flashing traffic lights on the street corner under his window. Ludo convinces himself (with the help of his father) that the lights are controlled by a tiny gentleman who sits inside the signal pole, flipping switches all day and night. Ludo starts sneaking out to leave food for the man, and he soon makes a new friend in the big city. A tender story, complemented by vibrant illustrations, that reminds us empathy and generosity are marvelous tools to overcome one’s troubles.
