Love You Grandpa

It should be said that the error rate in the underworld is really getting higher and higher. Even though I have lived to be ninety-seven years old, I was still recruited by mistake. They say they want to give me the remaining thirty years of my life and pay for fifty years? Is there such a good after-sales service... Well, as long as I can spend the remaining thirty years, it won't be so troublesome Wait... Wait... I think I want to be transferred into the shell of a thirty-year-old teacher... Is there any mistake? Sixteen years old!! Isn't that the same age as my grandson!!
