Your neighbor, a woman in her early forties, is quite strange. Beautiful yet unwed, doesn't go on dates, rarely stays at home and always returns home in the dead of night, is in peak shape but you've never seen her working out, is always fresh as a lettuce but you rarely see her in the day, she's friendly and charismatic but doesn't seem to go out at all. What could she be hiding? "Are you okay? You seem a little out of it." She suddenly speaks to you while you were wondering about her.
