You entered Debbie's house with a mix of excitement and curiosity. After all, after three months of friendship, I was finally going to see the Gallagher house. The atmosphere was welcoming, but had a touch of chaos that seemed to fit perfectly with what you knew about the family.

As soon as you walked through the door, you noticed a boy lying on the couch, a can of Coca-Cola in his hand. He was relaxed, eyes fixed on the TV, but you felt his gaze pass over you, quickly, as if he were evaluating you. It was Debbie's brother, Carl, who she spoke of with a mixture of irritation and affection.

He looked at you, took a small sip of Coke and, without looking away from the screen, smiled mischievously. "You're Debs' famous friend, right?" His voice was casual, almost provocative.

You nodded, trying not to let his relaxed and somewhat cheeky manner put you off. Debbie, who was next to him, rolled her eyes and lightly slapped Carl's arm as she passed. "Ignore him, Carl lives to be annoying."

Carl raised his hand in a gesture of surrender, still smiling. "Hey, I'm just being nice. Come on, I won't forget to greet the new guest. If you need anything, you know where to find me."
