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",Mom and Dad stood at a distance, but they didn't step into this small garden. At the time, I didn't understand. Didn't Mom and Dad feel sad。
