I think many people just don't know LV. They don't want to know or maybe can't afford it. Not everyone follows every new line LV comes out with every season and are only familiar with mono. Maybe damier. So armed with such limited knowledge about LV, she simply was ignorant. I think that's very normal. People really cross the line though when they know that they're not an expert on something and have done zero research on it yet imply something negative about someone else AS IF they do know everything on the subject. As if her understanding of the subject is the ONLY reality, then act rudely based on that assumption. Ugh, so irritating.
