Alberto, Lele's only grandchild, runs away from home and takes refuge at the Martini house because his parents are divorcing. Meanwhile, Grandpa Libero, to save money, starts selling musical pillows. Maria's birthday is coming up and she asks her father if she can celebrate alone with her friends. Lele agrees but is reluctant. Around the same time, Maria gets her period, and Rebby is the first to know.
