"But after seeing people fighting for gaga, it was like my eyes has been opened wide and a great fear had made its way in. As I ran down the trail toward my house, I felt it grow inside me like a fist around my stomach. Once I stopped at the storage room door, it tightened its grip: out of the five bags we'd filled with grain, only two were still there. In my mind, they were already gone."
