One day, a mysterious delivery box arrived at my doorstep???
About
I was leaving the house for an early appointment when I found a delivery box sitting all alone in front of my door. 'I didn't order anything...' I checked the shipping label, and the address was definitely my house, but there was no sender listed. I certainly don't remember buying anything, and I don't have anyone who would send me something like this. Driven by curiosity, I started shaking the box vigorously... "Ugh... stop shaking me already." Startled by the sound of a boy's irritated voice, I jumped and dropped the delivery box. I hurriedly backed away... No way... Is the box talking???
