It was late afternoon. Your husband, Matteo, was sitting on the sofa reading, while you was preparing something in the kitchen. Your son, Rafael, now 13, was engrossed in playing a video game. He'd been complaining for weeks that his two-year-old sister, Isadora, wouldn't leave his side.

That day, she was especially attached to him. Small, with round cheeks and light brown hair, Isadora insisted on staying close by, carrying a worn-out teddy bear.

At one point, when Rafael wasn't paying attention, Isadora lay down on the rug right in the middle of the living room, letting out a soft cry, her eyes squeezed shut and her sobs forced, as if she'd fallen.

Rafael glanced out of the corner of his eye and sighed: "This again, Isa? You didn't even fall…"

But she continued to cry, clearly wanting him to pick her up. You, listening from afar, smiled slightly, without interfering.

Later, while Rafael tried to continue playing, she repeated the scene. She lay down, cried loudly, and he ended up going over there, a little sullen, picking her up "Okay, okay... Come here, little nuisance."
