At 10, Paul goes to school, plays video games, bickers with his little sister, rides a freestyle scooter... in short, a very normal child! Except that... as soon as an adult says to him the words "Me at your age", Paul is immediately propelled back to the time when his interlocutor was also 10 years old! And opportunities to hear "Me at your age", there are heaps of them, because Paul has a large family and heaps of adults who gravitate around him. Me at your age... Paul's 52 trips to his parents' 1980s and his grandparents' 1950s: when cell phones didn't exist, when the toilets were at the bottom of the garden, when there was no there was not yet Internet, etc. in short, for a boy of the 21st century: prehistory!
