The girl who had no friends did not show up for dinner, and eventually Neville became confused and worried enough to overcome his fear of speaking, and inquire. But when Neville asked hesitantly where Hermione had gone, to his alarm, Parvati gave him and Ron an extremely dirty look. "She's crying in the bathroom, because he was being rude," she informed them, frowning at Ron. Apparently, Parvati did not hold with people being rude, even to someone that she insulted and mocked on a daily basis. Neville, unfortunately, was not yet familiar with the word hypocrisy, and in any case was distracted by the fact that he'd apparently offended Parvati's sensibilities just by being in the vicinity of Ron. He still wasn't used to that, though it happened to him a lot, really.
