Luna watched with a smile on her face as ponies bowed or gave respectful nods as she walked past them on her way through the Canterlot market square, enjoying the rustle and bustle, the bartering, the hollering shouts of ponies trying to sell their goods and make it clear just how much better their products were than that other guy twenty metres away.
While she wouldn't fully admit to it, she still found herself a little perturbed by the lack of bowing. Sure, there were some ponies that still did it - for which she was thankful - but it was difficult to just throw away the old ways and embrace how things were now, a thousand years after her banishment. She did her best to not let it grate her, but every now and then she found herself needing a bit of time without any pony around her just to make sure that she wouldn't unintentionally scare some mare, stallion or filly by asking them why they weren't bowing for "Your Princess of the Night". She didn't always make it to a secluded area, however.
So while she was trying her best to embrace the world of 'today' and not the one of yesterday, or rather, the day of millennia past, she did sometimes find herself having a minor relapse.
She returned a nod to a stallion working a market stall filled with mangos, papaya, and an assortment of other exotic fruit, and then stumped over something.
She just barely managed to catch herself and not fall over like a ragdoll, and then looked down to find a small cream coloured filly pegasus.
"My apologies, Little One, I did not see where I was going," Luna said, giving her the warmest smile she could. She still couldn't do it as well as Celestia, but then again that's what lessons are for.
The filly shook her head and blinked, looking up at her with an innocent yet apologetic look on her face. "No... I'm sorry, I just wanted to ask you a question... I-If that's alright?"
It was a surprise, to be sure, that somepony came up to her for the sole purpose of asking her a question, and a filly no less. Usually all she got was the grovelling of greedy nobles. With the smile on her lips widening ever so slightly, she waved a hoof, indicating that the filly could ask. "Speak forth, Child."
The filly blushed madly at this, apparently not having expected to be allowed to ask a question of Princess Luna so easily. "Well... My big brother told me something and I wanted to make sure it was true, so..." she paused, pawing awkwardly at the ground.
"Do not hesitate, you can ask me anything."
"Alright... He... My big brother said that..." her blush somehow deeped and she frantically blurted out the question in her hurry to get it over with. "Isittruethatyouaremadeoutofcheese?!"
Luna blinked once, twice. "...What?"
