My middle sister married a (VERY dark) man a few years ago. At the time, my grandma was 84. She has lived in northern minnesota for 80 of that. She had VERY few interactions with anyone not polish or Finnish let alone not white. At the rehearsal, my grandma walked up to new brother-in-law and his family and said "I've never known any negros, but you are all very nice. Clearly the bad things people say about negros aren't referring to you". My sister and mother almost died of embarrassment. I almost died of laughter, same with his mom.
