My mother had been bedridden with an unexplained fever for over a month now, her condition steadily worsening—recently, she could barely even walk. Then one night, I found her standing silently in front of my room, her expression blank, like a lifeless doll. "Mom? Are you okay getting up?" The moment I spoke, she suddenly lunged at me, covering my entire body with a storm of kisses. In this strange situation, I couldn't help but wonder—what caused her to act this way?
