Hi, this is started as a drabble, but it ended up being a bit longer. It's more of a feel-good family oneshot, but you could take it as somewhat US/UK if you must. It might be hard, but you are welcome to try :D

The American had the full attention of everyone in the crowded room. As he spoke, all nations listened, even those who didn't agree. As his powerful, enthusiastic voice went on about the merits of a new trading bloc, Arthur allowed his mind to wander.
Had it been that long since the nations of the world listened to him in such a way? He glanced around the room at the rapt faces, all obviously hooked on Alfred's every word. Arthur searched his memories. Had anyone ever listened to him in such a way?
"Iggy, when are you going to come visit me again?" The little boy representing Arthur's large colony pulled at the Englishman's trousers in an attempt to slow his departure, if only by a moment or two. "I miss you so much when you leave, and so does Mattie!" Arthur glanced at the blonde toddler, currently clutching a polar bear his size tightly to his chest. Canada had yet to speak a word of English, so Alfred's words fell a bit flat.
"I'll be back sooner than you think," Arthur lied smoothly as he ruffled America's golden mop of hair. He could already see tears beginning to pool in the sky-blue eyes he knew so well. Arthur really didn't know when he'd be able to make it back to the new World, but he did know it wouldn't be for years. Guilt burned at his chest, mixed with a slightly paternal feeling he didn't recognize at first.
Oh, just something to get the poor child to sleep. "Here, lad, let me tell you a story." The young America brightened at this, and jumped up onto the one bed furnishing the sparse cabin. England sat on the edge of the mattress, searching his brain for a good tale.
"Come on Mattie!" Alfred gestured to the toddler, who didn't understand his words but recognized Alfred's enthusiasm. He helped him up onto the bed and cuddled beside him, not afraid of the bear now sharing their bed. When they were all settled, Arthur began.
"Once upon a time, in a country far away, there lived a young boy named Arthur," the Englishman began softly, recounting the tale of the grand King who bore his name.
An hour later, the two colonies were fast asleep, despite America's best attempts to pay close attention. Arthur quietly got to his feet and stepped across the rough wooden floor on his way out of the cabin. He opened the door as quietly as possible, trying to avoid the creaking sound he had noticed then he arrived. To his relief, the Englishman was able to exit without waking either colony. Especially, America, who was sure to create a scene.
Before he left, he glanced behind him. His boys were visible through the frosty window, the very picture of warmth. Arthur's heart glowed at this scene, warming his body despite the harsh New England winter. He really shouldn't wait so long in between visits, he thought to himself.
Arthur started from his reverie as America mentioned his country, but it was simply in passing. Fully awake again, he saw that even after a solid hour of economic talks, their allies were still breathing in the words of his little brother. His almost-son.
Alfred glanced his way, and gave a nod in his direction, acknowledging him with a slight smile, probably unnoticeable to most of the other nations. Arthur smiled to himself as he realized it didn't matter that he no longer had the attention of the world.
He had the attention of someone more important.
