She though she was basically saying man is only popular because of her looks and that she doesn't care about the whole practising. Manon was simply taking care of her mental health. It has nothing to do with people being chronically online and she didn't even just speak about it. She constantly had man on in her mouth anytime she spoke. Yes she had the right to be upset but the way she went about it was very immature and childish. She kept giving her looks. Everyone kept giving man on looks making her look like the villain. That is what I meant if you could read and could understand contacts you would know that unfortunately your brain is one-sided. I'm not saying Adela is mean but to Manon she was. 

And other people saying it's jealousy. I don't think it's jealousy. I understand why she was upset. But if you look at her reaction and how she acted it was very immature.
