Silly
"Am not!"
"Are too!"
"Nuh-uh!"
"It's true!"
"It is not!"
"Is!"
"Not!"
"Is is is is is is!"
"Not not not not not!"
Rarity cleared her throat. "Hello, my little ponies. What seems to be the problem?"
"Hi, mom," a filly piped. "Star Thunder said that I'm an..." She cringed and suck out her tongue in a badly faked disdain. "Egghead."
"Are too!" Star Thunder argued back. "You say you read a lot, and my mom said you're an egghead, just like her! And you spend a lot of time in the library as well!"
"Am not!"
"Are too!"
"Moooom!"
"Silver Streak, what have I told you about arguing with ponies? Especially with Star... because... you-know-what..."
"But moooom..."
"No buts, missy."
Silver Streak sighed and looked at her friend. "I'm sorry, Star."
Star Thunder stuck out her tongue in response. "You don't need to apologize just because I'm blind... egghead."
"I'm not an egghead!"
"Are too!"
"Not!"
Rarity sighed and floated a few bits out of her saddlebag. "I have a better idea for you two. Instead of arguing, why don't you two go for a milkshake?"
Silver Streak grinned and opened her pouch, watching in awe as a few shiny gold coins landed in it. "Thanks, mom!"
Star Thunder giggled. "Told you it'll work!"
"Hey, it was my idea!"
"Was not!"
"Was too! Race you!"
"Silver Streak, wait up! You know I can't go that fast!"
Rarity couldn't do much more than shake her head in the direction of the distancing fillies and flinched, as she felt a hoof on her ear. Startled, she quickly turned around her head and smiled. "You startled me, Applejack."
Applejack smiled and nuzzled Rarity. "Ah had to. Hadn't done so in a while, so Ah thought Ah might brush up on that a bit."
Rarity turned her head back to the distancing fillies.
"Let me guess... They did it again," Applejack groaned.
"Of course."
"What was this time?"
Rarity snickered. "Star Thunder said she was an egghead."
"I'd blame her mom for that," Applejack mused.
Rarity tilted her head and furrowed her brow. "Are you saying that I'm an egghead?"
"Maybe not as big as egghead as Twilight, but still an egghead."
Rarity snorted and stomped her hoof. "Applejack! I'm deeply insulted! I want you to take that back!"
"Er... what?"
"No? In that case I'm taking your hat!"
Rarity's horn flared, lifting Applejack's hat way above the pair.
"Hey! Ya stole my hat! And Ah-Ah... Am taking yers!"
With quick moves, Applejack stretched her hooves, grabbed Rarity's hat, and put it on her own head. "There!"
Rarity laughed softly at the image before her. "You look absolutely adorable, Applejack. Why didn't you tell me that you wanted to pursue a fashion career? You know I could help you with that..."
Applejack's cheeks flared up in embarrassment. She attempted to get rid of the hat, but she was too late. A light blue glow already removed it from her head and returned it to the rightful owner.
Applejack groaned.
"Aw, come on, Applejack. Don't tell me you forgot how to have fun... I know it wasn't like that few days ago..."
Applejack sighed. "Sorry, Rarity... Ah had a bad day..."
"Oh," Rarity replied in a low voice. "I think I know how to fix that..." Her magic returned back her hat as she leaned and let her muzzle touch Applejack's. She brushed her lips against hers, the gesture shortly forming a deep and passionate kiss.
After what felt like minutes, Rarity broke their kiss, nuzzling her mare's path towards the ear, and stopping. With the sweetest voice she managed to muster, she whispered, "Tag. You're it!"
