In this translated picture book, a young boy meets a new friend who helps him cope with his parents' separation.

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 liveliness of the apartment's neighborhood and the consistency of the flashing traffic lights on the street corner under his window. Fascinated by these lights, Ludo convinces himself (with the help of his father) that they are controlled by a tiny gentleman who sits inside the signal pole, flipping switches all day and night. Worried about his well-being, 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.
