What accurate fortune-telling experience do you have?

My grandmother, who can calculate divination, lost her book when she was a child. She asked grandma what to do if she lost it. She made an offhand face, and the storyteller was there. Later, I went to find it, and it was at that classmate's place. I didn't take it seriously at that time. Later, I grew up and had several boyfriends. My grandmother told me her appearance, height and personality on the basis of never meeting each other. When I met my husband, I asked my grandmother for advice. My grandmother also told me her husband's height and appearance accurately, and even her husband's parents' personality. Let me not miss it. (She didn't say that in front of her boyfriend) Now that I'm married, my mother-in-law is super nice.
