Since I can remember, my grandfather has always been trying to please my grandmother.,If my grandfather is really that impressive, how come my grandmother just needs to give him a look and he becomes as obedient as our big golden retriever at home,At that time, I already found it unbelievable. I ran to my dad's bedroom and blurted out, "Is grandpa a pervert I saw him holding grandma's feet. Does grandpa have a foot fetish"。
