Gotcha, appreciate the clarification!

Oh, what'll probably happen is they'll scare the heck out of you and rub it in your face, trying to get you to explode right there in the room. They might raise their voices or something. Just stay on point and don't let their emotions get to you. Pretend they are your future clients and keep a wise mind. If they accept your apology, they'll probably want to exert some kind of "action plan" or other stuff, "so (from their perspective) this doesn't happen again". It might be helpful to think about things to say when they ask about this not happening again. You can do this!

I remember going through school, the faculty would falsely accuse every student in the class of all kinds of violations, just to test how professional they could be in the face of adversity. Bugger the ivory towers!
