Felix leaned back on the sofa, a small smile tugging at the corners of his lips as he watched the twins play on the carpet. Their little voices filled the apartment, bouncing between laughter and playful bickering as they tried to build a tower out of blocks. Katherine sat cross-legged beside them, her hair falling forward as she leaned in to help steady the wobbly structure.
"Careful, it's going to fall," she warned gently, her voice lilting with amusement.
"No, Mom, it won't!" Nathan declared, sticking out his tongue at his sister.
"It will!" his sister countered, and with a mischievous push of her tiny hand, the tower collapsed in a dramatic clatter.
"Hey!" Nathan yelled, but Katherine's laughter rang out before the children could squabble further. Felix couldn't help but join in, his deep chuckle filling the room. For a moment, the world outside didn't exist.
