With two disastrous "lessons" behind them, the sisters decided to try their luck at... anything.
Baking? Luna charred the cake.
Gardening? Celestia got dizzy from mixing various scents.
Music? Luna nearly blew Celestia's ears out with metal and Luna wanted to retch at Celestia's choice of bubblegum pop.
Dancing? Were they supposed to step on each other's hooves so much? At least, they could agree shaking one's hindquarters was not dancing.
As a last resort, they even had a small contest of doing air tricks. Which promptly ended in less than five minutes when they slammed into each other and landed in a compromising position sisters should not ever be in.
"Seems all we've achieved is a close-up view of each other's hindquarters," Luna grumbled as she and her sister washed themselves off.
"Are you upset?" Celestia asked, worried.
"Aren't you, sister? I'm certain this is not what you had in mind for our day off together. 'Tis been nothing but a disaster."
"No, it hasn't! This has been the best day I've had in a long time!" Celestia exclaimed.
After being able to pick up her dropped jaw, Luna asked, "Sister, did you sniff too much of the lavender?!"
"It isn't what I had in mind, but we hadn't agreed on anything to begin with," Celestia said. "It certainly broke the monotony I've adjusted to."
Luna almost couldn't believe what Celestia was saying. Nothing had gone right in the slightest. Every single activity blew up in their faces, some literally. Yet Celestia was happy?
"Luna, I wanted to spend a day and night with you. That's it," Celestia explained. "It didn't have to be perfect. Did you really not have fun?"
Luna thought about it. Not a single thing had gone right. But in the end, she and Celestia had been able to laugh it all off. Sure, they'd gotten hurt a few times, but nothing beyond a small bruise at most. It was kind of funny when she really considered it. In a way, it even reminded her of how they played as fillies, getting so rough and making mischief together.
"I did enjoy myself," Luna finally answered with a smile. "It would be a lie to say I'm upset."
"Although, we haven't eaten since breakfast, so let's have lunch," Celestia suggested.
"It's rather late for lunch," Luna said, pointing out the window. Evening had fallen and it would soon be time for Luna to raise the moon.
"Dinner then," Celestia decided.
"Go on. I will start lining the halls."
"Oh, well, if you are going to line the halls with lavender right now, may I join you?" Celestia asked.
Luna looked surprised for brief moment, but smiled again. "Of course, sister."
"22... 23... 24. I did not know this hall could hold 24 bouquets," Celestia remarked.
"It is our biggest hall, so I find it fitting," Luna explained.
Celestia took a bundle of the lavender remaining in the cart, circled it, and placed it atop Luna's head. Luna liked it and used another bundle to make a necklace she placed around Celestia's neck. Celestia took another turn, making four anklets out of a lavender bundle for Luna. In return, Luna lined Celestia's shoes with some of another bundle.
The sisters realized they'd made a game and, for the next several minutes, had fun creating shapes out of the lavender, gradually getting larger and larger. At one point, Celestia made a long rope of it and spun it around Luna, telling her to jump each time she would move it under her feet. Before they knew it, they were both skipping over the lavender-made rope, laughing and enjoying themselves like fillies. Luna even created a second one to make the "skip lavender-rope" game a little harder, but more fun.
By the time they tired of their created game, Luna was almost late raising the moon. After she hurried to the balcony to bring up the moon, she followed Celestia to the kitchen for them to make dinner.
"What gave you the idea to make shapes out of my lavender?" Luna asked.
"Nothing in particular," Celestia answered. "It was an attempt to make you laugh. I don't think we did such a thing since we were small ourselves, sister."
Celestia pulled a few bunches of fruits and vegetables from the fridge. Luna simply watched, but Celestia passed a few of the bunches to her, as well as a few skewers.
"One more try?"
Luna hesitated for a moment before taking a skewer in her own magic grasp. "One more."
The recipe was an easy one, but this time around, Luna was more careful in mimicking what Celestia did. She diced everything Celestia passed to her perfectly, she set the temperature on the stove just right, she monitored the time, and she had no trouble placing the finished food on the skewers. Turned out Luna only needed some patience to be a good cook.
"What are these called, sister?" Luna asked as they sat together at the table.
"Kabobs."
"Why do ponies of this time place sliced food on pieces of wood?" Luna asked, giving her food a cynical glare.
"Try it," Celestia laughed. Luna placed the wooden skewer in her mouth and pulled off the fruits and vegetables. To Celestia's amusement, she kept her cynical glare, but a smile later proved she liked it.
"These kabobs are delicious! How many did we make?"
"Twenty."
Luna hastily took nine more and wasted no time in devouring them. "The deliciousness has been decupled!" When Celestia responded with the funniest confused face Luna had seen her make, she explained. "It means ten, sister. Two-in-tens for you?"
"Luna, no!"
