On leaving school, Teo and Susan see how a group of firemen rescues a cat that is trapped on the top of a tree. Once the rescue operation is finished, the fireman shows them the car, how to turn on the siren and how to open the fire hose. Teo and Susan are impressed. Maybe you would like to go for a walk on this car?, asks the fire officer. Our friend accepts delighted. Once they are inside the car, a fireman loans his steel helmet to Teo. It’s too big for him! Susan laughs heartily. People lock at them and say hello to them when they pass. The firemen take them to the entrance of Teo’s house. At night, Teo tells his father his adventure. When he grows up, he wants to be a fireman. To put out fires and help the others is a nice job.
