For some reason I picture her as less willing to admit the possibility of being wrong than that. No, it's probably because of the way she jumped in and loudly whitesplained for the clueless teacher about Jews and their shocking belief that Jesus is neither a deity nor, according to her, a prophet. And her immediate readiness to answer questions as an authority on Judaism that is so ready I couldn't actually get a word out before she started. Or during. Anyway, I have a nightmare vision of her just denying if, for example, I pointed out that the Romans were responsible for the crucifixion ("But the Jews were responsible", "But it says they were in X," "But it totally DOES say that", "Well, it doesn't matter that crucifixion was for political crimes, it just WAS because some Jews asked"). I feel this is a Finnish response to contradiction but I might just be projecting from negative experiences with my mother-in-law.
