Dangerously Close to

I only know that my grandfather adored my grandmother, to the point of being "crazy" about her.,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",It's not because I'm afraid of my grandmother, but because my grandfather favors her. This is common knowledge in the family.。
