As the service drew to a close, Sarah lingered in the church foyer, engaging in conversation with members of the congregation. Among them was Mrs. Petrov, a Russian woman whose family had emigrated from Moscow some time ago. Sarah had always admired Mrs. Petrov's quiet strength and unwavering faith, who always gave solace in her presence during moments of doubt and uncertainty.

"Sarah, it's so good to see you," Mrs. Petrov greeted her with a warm embrace, her eyes sparkling with kindness. "How have you been?"

"I've been well, thank you," Sarah replied, returning the embrace with a smile. "How about you? How's your family?"

Mrs. Petrov's smile widened, a sense of pride evident in her voice. "We've been blessed," she replied. "My son Nikolai just started college, and my daughter Anya is doing wonderfully in school."

Sarah's heart skipped a beat at the mention of Anya, her 'best friend', who always causes anxiety whenever she is around. Despite their different backgrounds and upbringing, Sarah and Anya has forged a bond that transcended barriers, their shared secret drawing them together like kindred spirits but not in a traditional way.

Anya always said that quote to Sarah multiple times whenever Sarah broached on the topic of not being friends and maintain healthy distance with one another. Sarah remembered that quote one more time, 'Keep your friends close; keep your enemies closer', by Sun-Tzu who was a Chinese general and military strategist. Sarah was beginning to hate Sun-Tzu just because of Anya.

Mrs. Petrov, who was not aware of Sarah's internal turmoil at the mention of her daughter's name, called her daughter towards them. Anya came towards them when heard her mom call her name. Anya's smiled intensified when she noticed who her mother was talking with.

"Sarah, how are you," Anya greeted her with a sarcastic smile. "Did you enjoy the "inspiring' sermon?"

Sarah forced a smile, her eyes flickering with a hint of distrust. "Absolutely," she replied, her voice tinged with forced enthusiasm. "The sermon conducted by Pastor Miller was really 'inspiring'."

Anya nodded, her gaze lingering on Sarah's face for a moment longer than necessary. "I thought so too," she replied.

Sarah and Anya exchanged pleasantries, their smiles masking the undercurrent of tension that simmered beneath the surface of their friendship.

As they chatted, Sarah couldn't help but feel a pang of resentment towards Anya, her so-called best friend. Beneath their facade of camaraderie, there lurked a mutual distrust, a silent acknowledgment of the secrets they harbored.

"So, Sarah, how was your weekend?" Anya asked, her tone casual but her eyes probing for any hint of deceit.

"It was fine, just the usual," Sarah replied, forcing a smile as she carefully measured her words. "How about you? How's everything going with your family?"

Anya's lips curved into a smile, but there was a hint of tension in her expression. "Oh, you know how it is," she said vaguely. "Just trying to keep everything together."

Sarah nodded, a knot forming in the pit of her stomach. Beneath the surface of their conversation, she knew there was a deeper layer of meaning which was a silent exchange of information that went unsaid but was understood between them.

They continued to chat, their words laced with an undercurrent of anxiety that neither could shake. Every sentence felt like a delicate dance, a careful tiptoeing around the truths they dared not speak aloud.

"So, Anya, have you heard about the new substitute teacher for our class?" Sarah asked, her voice carefully neutral.

Anya's eyes narrowed slightly, a flicker of suspicion crossing her features. "I've heard a few things," she replied guardedly. "Why? What have you heard?"

Sarah hesitated for a moment, her mind racing with thoughts of the secret they both harbored. "Nothing specific, just that the teacher might be nice," she said evasively. "I was thinking maybe we could ask the new substitute teacher to allow the formation of our own after school 'club'."

Anya's expression softened, a flicker of understanding shining through her guarded facade. "That sounds like a great idea," she said, her voice tinged with genuine enthusiasm. "I'm sure it will work out."

Sarah couldn't shake the feeling of unease that gnawed at her insides every time she chatted with Anya. But amidst the anxiety and uncertainty, there was a flicker of something else, a glimmer of what could have been if not for the secrets they kept hidden. She felt a pang of loneliness that gnawed on her. It was a longing for the genuine connection that had eluded her for so long since she came to this world. 

Sarah couldn't help but wonder what their friendship might have looked like if they had been able to trust each other completely. If they had been able to share their burdens and fears without fear of judgment or condemnation.

But as they exchanged pleasantries and forced smiles, Sarah knew that their friendship would always be tainted by the knowledge of the secrets they harbored. And as much as Sarah wished things could be different, she knew that some truths were too dangerous to share with anyone else including this community.

Anya's smile faltered for a moment when she noticed something inexplicable from Sarah, her gaze flickering with uncertainty. "Is everything alright, Sarah?" she asked, her voice tinged with concern.

Sarah plastered on a smile, her tone saccharine sweet. "Of course, Anya," she replied, her voice dripping with false sincerity. "I'm just looking forward to spending time with you after I inform my parents."

Anya nodded, her expression knowingly. "Yes, me too," she replied, but her voice tinged with a hint of skepticism because she knew what Sarah was really planning to do in the name 'spending time'.

As Sarah told Anya to wait for her at the entrance, she went towards her parents who were talking with the other members of the congregation. With a sense of anticipation and apprehension, she broached the subject with her parents with her voice being steady and resolute.

"Mom, Dad, I was wondering if I could go over to Anya's house since the service is over," she began, her heart pounding in her chest. "We have a project for school that we need to work on together."

Martha and John exchanged a glance, their expressions thoughtful. After a moment's consideration, they nodded in agreement, their trust in their daughter evident in their eyes.

"Of course, Sarah," John replied, his voice gentle. "Just be sure to be home in time for dinner."

Sarah smiled, a sense of relief flooding her senses. "Thank you, Dad," she replied, her voice tinged with gratitude. "I won't be late, I promise."

With her parents' blessing secured, Sarah said her farewells to the other members of the congregation, her heart fluttering with anticipation for the day ahead but also heavy with the weight of the secrets hidden by her.
