"She seems to possess a tense relationship with her daughter and is initially seen as being unsupportive of her, either being completely oblivious to her daughter's interests or aware of them but giving Rose gifts that she hates on purpose. Rose believes her mother is constantly making her life miserable through cruel irony. However, she has been speculated to have more empathy for her daughter than she lets on." -Homestuck wiki

She is an alcoholic and always drunk so take that as you will when giving her a voice.
