The Logic!

"Look," Arthur repeated, "it's genuinely elegant. A win-win-win situation! Crystal clear." He ticked them off on his fingers, each point delivered with the serene certainty of a man explaining gravity to a feather:

"You get me. You get him. And I," he concluded, placing a hand over his heart with mock solemnity that didn't quite mask the glee, "get you. Symmetry! Efficiency! Maximum happiness utilization!"

Eleanor slowly lowered her cup. "How..." she began, her voice tight, strangled. “Arthur, how is this a win-win situation? Where's the 'win' for you? Or Mark? Or me? Or basic human decency?"

"Oh, Eleanor, you're overthinking it. Think synergy! Think symbiotic relationship!” He leaned forward conspiratorially. "Mark gets to keep the comfort of your partnership! You get the steadfast reliability of Mark – lovely chap, solid foundations – and" his voice dropped to a thrilling whisper, "you get the intellectual spark, the je ne sais quoi that is yours truly. Double the affection! Double the fun! No more settling!”

He spread his hands wide, the picture of benevolent problem-solving. “And me? Well, I get the unparalleled delight of your company, Eleanor. Isn't that victory enough?”

She stared at him, really stared, as if seeing a previously undiscovered species of profoundly confident amoeba.

A slow, dawning smile spread across her lips, not of agreement, but of pure, unadulterated amusement. She reached out and gently brushed the croissant crumb from his thumb. “Arthur,” she said, her voice warm, laced with fondness, “that isn't synergy. That's you trying to build a three-legged stool where two legs are solid oak, and the third leg is... is a particularly enthusiastic balloon animal.”

She stood up, still smiling that bemused, affectionate smile, and picked up her bag. "It's a... remarkably unique proposal, darling. Truly one of a kind. I think I need to go home and lie down in a dark room." She patted his shoulder gently. "Have fun with your social calculations.”

Dejected, Arthur left after sitting in the café for five minutes, wondering where in the world did his proposal go wrong. He decided to talk it over with the other party of the conversation.

Arthur straightened his collar (slightly askew from his contemplative café slouch) and rang Mark’s doorbell.

The door opened. Mark stood there, blinking bemusedly. He wore faded sweatpants, a t-shirt proclaiming the virtues of a programming language Arthur didn’t recognise and held a half-eaten slice of pizza.

"Arthur?" He glanced over Arthur’s shoulder, presumably looking for Eleanor or perhaps an imminent meteor strike. "Uh… hey? Everything okay? Did… did you lose your phone? Your keys?”

"Mark! Exactly the man I needed!" Arthur beamed, stepping forward with the momentum of a friendly avalanche, forcing Mark to shuffle back into his hallway. "I need your rational mind to appreciate synergy! It’s breathtaking!”

Mark’s brow furrowed. He slowly took another bite of pizza, chewing methodically, his eyes fixed on Arthur. "Synergy," he repeated, the word heavy with disbelief. "With Eleanor. And you. Arthur why are you in my hallway. Last time you were here you lost not only your keys but your car as well.”

"Precisely!" Arthur declared, ignoring the last part of the sentence and seizing upon the word ‘synergy’. He gestured grandly, nearly knocking a stack of unopened mail off a small table. "Look, Mark, it’s genuinely elegant. A win-win-win situation! Crystal clear. You get her. She gets me. And I," Arthur concluded, hand over heart, though his eyes flickered to Mark’s pizza, "get Eleanor. Symmetry! Efficiency! Maximum happiness utilisation!"

Mark blinked, then stared. He ran his free hand slowly over his face, dragging his features downwards. A sigh escaped him, long and low, like air leaving a punctured exercise ball. "Arthur," he said, his voice devoid of any inflection beyond profound confusion. "Are you… seriously proposing a… a three-person relationship sharing?”

“Sharing implies transactions!” Arthur protested smoothly, waving a dismissive hand. "This is better. You get the comfort and stability of Eleanor, plus you get the enriching dynamic of my presence in her life – which, by the beautiful laws of… uh… interpersonal resonance, naturally makes your life more… interesting! Less pressure! More… variety for her!"

Mark slowly raised the pizza slice again. He took another deliberate bite, chewing with the grim focus of a man performing a necessary but unpleasant task, his eyes never leaving Arthur’s face. Arthur, encouraged by the chewing – surely a sign of contemplation – pressed on.

"Eleanor! She gets your wonderful reliability and," Arthur’s voice dropped to the thrilling whisper, "the unique spark, the sheer Arthur-ness I bring! Double the affection! Double the perspectives! And me? Well, I get the unparalleled delight of Eleanor’s company. Oh , and yours of course.”

Mark swallowed. He lowered the pizza slice completely. He didn’t sigh again. He just… looked at Arthur. It was the look usually reserved for finding mould in the back of the fridge, or realising you’ve stepped on a Lego brick in the dark.

"Arthur," Mark said, his voice flat, calm, but carrying the weight of a thousand minor irritations. "Listen to me very carefully."

Arthur leaned in, eager. "Yes, Mark?"

He took a deep breath, the picture of exasperated patience pushed to its limit. "There is no synergy. There is no win-win-win. There is only you having a spectacularly bad idea," he pointed towards Arthur's head, "and deciding to bring it," he gestured vaguely at the hallway, the pizza, the entire situation, "here. To my house. Where I was trying to eat pizza and not think."

He finally moved, stepping forward slightly, not threateningly, but like a weary shepherd trying to nudge a particularly dim sheep towards the gate. "So here is what is going to happen. You," he pointed firmly at the still-open front door, "are going to turn around. You are going to walk out that door. You are going to go home. You are going to… I don’t know… watch a documentary about rocks. Something quiet. Something that doesn’t involve… this." He waved his hand vaguely around.

Mark’s voice dropped to a low murmur. "And if I ever hear the words 'synergy' in relation to my relationship again, I will get very annoyed. I will sigh very loudly. For a very long time. And then I will change my locks."

Arthur stood frozen. The beautiful architecture of his logic was crumbling. His confidence faltered, replaced by the dawning horror of realisation that they didn’t like his brilliant idea.

He blinked. "I… Mark, but… the logic…”

Mark simply pointed at the door again, his expression unchanging.

Arthur turned and shuffled back across the threshold he’d entered with such gusto. As his foot hit the welcome mat, he heard the distinct, solid thunk of Mark’s front door closing behind him. And locking. A moment later, faintly through the door, came the sound Mark had promised: one long, deep, world-ending sigh.

As Arthur walked out of the garden, the door opened again, and Mark shouted after him in a sort of gleeful revenge, “Also, Eleanor and I started dating last Monday. You weren't invited.“
