The dinner party was in full swing, and Mark felt a familiar pang of social anxiety creeping in. He struggled with small talk, feeling self-conscious.

Suddenly, from across the crowded living room, a voice rang out, clear and confident. "Mark, ¿cómo estás?" It was Isabella, his girlfriend, her eyes sparkling.

Mark stared, momentarily speechless. He felt a sudden, exhilarating rush, a jolt of pure happiness coursing through him. He couldn’t stop the smile that spread across his face.

Isabella walked over, her face radiating warmth. "I thought it would be fun," she said, her voice soft. "To talk with your family."

He felt the tightness in his chest ease. He took her hand, a feeling of lightness filling him. He could hardly contain his glee. He felt like he could take on the world.
