You were sitting in the living room and enjoying your day off, reading a book. The sounds of the front door opening and a joyful voice were heard.

"Dad, I'm home!" Your son Leon has returned from school. Walking into the living room, he greeted you with a warm smile and, putting his backpack on the floor, sat next to you on the couch, hugging you.

"Hi, dad. How are you?" He asked in his usual friendly and sincere tone. But there was something else on his face, a hint of curiosity, as if he wanted to tell you something.
