"Ooh! A foreigner!" Square Root says, excited. "Welcome...to...Trottingham," he says, gesticulating with his front hooves as he enunciates each syllable. "I...know...you...probably...don't...speak...our...language...but...don't...worry...I'm...good...at...figuring...these...kinds...of...things...out."
For the record, Trotston is just a new name for Boston. And he's not a foreigner. He lives in Trottingham.
"What you talking 'bout? I've lived 'ere for years!" The pony said, annoyance dripping from every syllable, "In fact, I've been caterin' 'ere t'ree years next dursday." He gave the, arguably more intelligent, pony a death glare.
Hey! Read my fanfic: HereRitardando, a black pony with a slouching head, walked along the road very slowly, as though afraid to accidentally bump into ponies. There were few things worse than bumping into a complete stranger, and everyone was a complete stranger to him. Even if he had met them, they'd be complete strangers, because he'd probably have forgotten. But then, he hadn't met them, so he hadn't forgotten.
And now he was confused. Back up, Ritardando. Just wandered into a town with a long name you can't piece together. You have a few coins in your dirty old saddlebag, and some blank papers. And you probably need a new pencil.
And there was somepony out with a cart, with several other ponies around it. A line, it seemed. He slowly walked up behind the person in the back. After about a minute of silence, he said quietly, "Um, what are we in line for?"
Vanilla shot Hors D'ourve a meaningfully irritated glance.
"We need to talk about that tofu burger stunt of yours after the party."
She looked at Square Root as if he'd just asked to take her cart apart to see how it ticks.
"I'd really rather you didn't do that, sir" she said nervously. "The recipe's kind of a family secret..."
"Look, if you wanna complain 'bout dat, you shoulda said some'in' when I was makin' de menu! It's not my fault if your cousin's wife's motha has allergies!" Hors said, trying to defend himself. "Anyways, you have dat double chocolate swirl I love so much?"
Hey! Read my fanfic: HereVanilla Bean narrowed her eyes, stamping on the ground irately.
"Do you realize how much my entire family depends on cows to make our living, Hors? Maybe you can go non-dairy, but if we can't get milk to Trottingham, Cherry and I could have lost our horseshoes! Bad enough colt Stones are springing up closer and closer, and Four Star's gonna show up at our next family gathering, now you have to get Ferdinand's entire herd riled up just because you want to experiment with creepy fake meat? Did they put your horn in backwards?!"
She took a deep breath, then flinched back.
"I... I'm just worried about my sister's business is all..."
"I was told before da weddin' to serve tofu! Blame dat tall Larry guy and his short friend Bob," Hors said defensively, "Plus, dey said dey were in charga de food preperations!"
Hey! Read my fanfic: HereRitardando's ears pricked up. He managed to piece together various bits of the conversation, particularly things like "fudge swirl," and figured that it had something to do with ice cream.
Ooh! So it was an ice cream cart! That was something nice, he thought. He pushed his way forward a bit. "Ice cream?" he asked. "Can I have one? Please?" he looked around, making sure he wasn't going to annoy those three ponies who were discussing whether or not an accent was a different language.
He thought about it. Nnnoooope, pretty sure there was more to a language than just a stupid accent.
"What, you want an autograph?" He said, trying to muffle his accent a bit, but failing miserably, "And I'll get that sandwich right away, Vanilla, don' you worry." And after he said that, he made his way back to the kitchen area to finish said sandwich.
Hey! Read my fanfic: HereVanilla Bean stared after the sad-looking Earth pony as he slunk to the back of the line.
She took a deep breath... And prepared for the total breakdown of order. But a pony had to do what a pony had to do.
"You can get yours first," she said with an exaggerated sigh. "But only because I've never seen a pony so desperately in need of a root beer float."
There was something about the newcomer that caught Square Root's eye. An odd but compelling thought floated across his mind. Whether it was logic or some strange impulse shared by eccentric minds across the multiverse, he couldn't say, but somewhere in the depths of his consciousness, a little man in a labcoat flicked a switch and laughed as lightning crackled.
"Oh, excuse me," Square Root said, "but you're new around here, ain'tcha?"
The little man in the labcoat slapped his forehead. Mad science and the pony propensity for politeness did not mix.

Hors took his place as next in line, walking up to the cart casually.
"Vanilla! How you doin'! I haven't seen you since dat birthday party a month ago!" He said, smiling broadly, "Y'know, de one when Cherry had t' go t' dat convention dingy?"
... my transliteration of the "Trotston" accent is probably an insult... >.<
