I dont approve of how she reacted but I might know why she reacted the way she did
I think she might be in defense mode, when a lot of people tell you your doing something wrong you can go in denfese mode espically if it something you care about.
evry time someone point out my bad grammar I am about to blow because its a thing I am sentitive about. some are rude some are trying to be helpfull, evryone trigger me, and its not fair on those who try to help gets my anger.
and I think its kinda the same,
