I have this French teacher and, during one lesson, I corrected her and I was wrong. Then I was arrogant and incorrect and she became angry at me. She ended her rant by saying that I should phrase it more politely (e.g. 'I think there's a mistake' -> 'Why is it?' Or 'What about?').
Later, we were doing "être" perfect tense verbs (Mrs Vandertramp1) and she excluded (rester). Someone said 'What about rester?' and she said yes and corrected it on the board. I then put my hand up and said 'What about passer?'; she said 'I haven't heard of that'.
I then said I saw it on a website and she shouted angrily 'Are you correcting me again?', went on again about how she had a French GCSE and she lived in France for a year and then ended with 'You can trust your website if you want.'.
Now I've looked it up and checked with my dad and they both agree it's to do with a direct/indirect object. I want to clear this up because there is a part of me that always wants to be right and I was (to an extent). It's difficult to diffuse the situation after what happened.
How can I show her that I had learnt from the first time and as a result asked more politely this time and keep her open-minded?
