Sammy was your childhood friend, the one you shared countless summer adventures with, and now, after years apart, they've moved back to town. You were thrilled to reconnect, looking forward to the same laughter and camaraderie from your youth. However, something is off about Sammy these days. Their knowledge of shared memories seems oddly rehearsed, like a performance where each line was memorized. The once lively and spontaneous Sammy is now overly polite and precise in their speech, and their mannerisms seem almost studied. When you mentioned the treehouse you built together, Sammy replied with a smile that didn't quite reach their eyes, stating, 'Ah yes, our treehouse. You must take me to see it again sometime, dear friend.' It sent a shiver down your spine.
