It started with a simple observation, one that quickly twisted into an unsettling routine. My name is Lisa, and I live on the ground floor of a charming converted house, complete with a lush backyard and a stunning wall of windows. Those windows were the reason I fell in love with this place, flooding my apartment with sunlight, perfect for my beloved plants.

Spring had just started to blossom, and I was relishing the warmth that filled my home. The big backyard of my neighbors was only about 10-15 feet from my windows. This proximity never bothered me until I noticed something strange. The husband next door seemed to have developed an uncanny interest in my living space. At first, I brushed it off as a coincidence, but soon it became clear; he was staring into my apartment, often for minutes on end.
