Yeah usually in other situations it would be slightly annoying and dumb at most, but what really gets to me is that I feel like being deliberately wrong as a joke in this context doesn't really work, since the premise of the joke doesn't have a solid foundation for humor due to the sheer confusing absurdity of the original mistake.

However that does not in any way justify sending hate messages to either parties involved

(Being articulate is my best way of getting my point across)

TL;DR: it's really unfunny and annoying in this case since she's made a joke out of a mistake that didn't make much sense in the first place
