"You truly are ignorant, aren't you?" she asked, shaking her head. "Can't you even recognize nobility when you see it?"
Was nobility written on people's faces? Sure, the girl was beautiful with her curly blonde hair. She had that air of 'grandioseness' (yes) around her, but for Alexendra she was just like a younger version of Lefresne's mother without the power, the kindness, the innocent clumsiness, and the years on top. Ah yes, and she wasn't engaged to her daughter too so that was another point of difference.
"... she isn't like Fresne's mother at all actually," Alexandra concluded.
Sure enough, her mind was trailing far away now and the girl didn't appreciate that either – by mumbling random stuff with an unfocused gaze, Alexandra was basically ignoring her, saying that she was not worthy of her interest.
Another misunderstanding, but, then again, Alexandra WAS thinking that.
