@vrandecic Insufficient info to say. She said he was at the party at the time she said it ("he is at the party"), but when they got there - later - he was not. But perhaps he *was* there when she said that he was? She didn't say "he will be there all night", she said he was there at that moment. And we don't know if he was or not.
Yes, I am autistic, and yes I am fun at parties, why do you ask?
