"Rustling, rustling..." Waves of voices rang out and woke me up when I was sleeping. I rubbed my eyes and said impatiently, "Who is it, not sleeping in the middle of the night, but also let people sleep!" As soon as I opened my eyes, there was no one ah, it was clearly my toy saying - words. Wait a minute! The toy's talking! That can't be! Am I hallucinating? I rub my eyes again. Oh, no, is it really the toy talking? Then the piggy bank glared at me, and I turned over and pretended to sleep.
