I just found out that people within 20 IQ of each other can understand the other person well, but once you get out of that 20 IQ range, the smarter person starts sounding like gobbely-gook to the dumber person.
And there's also a point where the person with the higher IQ can't understand the person with the lower IQ.
I guess that's why I can't read books under my reading level and I can't understand a word my friend's friend say.
That, but she also says random things completely unrelated to the topic we're on (Just earlier today she we were talking about porcupines and she said I had carrots in my blanket? I don't know), repeats things she said literally seconds before, she won't listen to any sort of logic, and there's a bunch more.
