Not only she comes back unannounced, (judging by Sora's reaction, she didn't gave her a call or sms, that she would come back) but also starts right off the bat talking about moving away and having a new man, acts all happily and motherly only to switch to her evil, abusive side when her daughter shows a tiniest sign of disobedience and to top it all off, she doesn't even asks Sora about her well being, if she eats healthy, if she's attending school, if she made some friends. Nothing at all. Only cares about money and status... One of the worst types of parents...
Sorry for bad Eng...
