I never like the feeling of parting with someone else, unless it's someone I don't fancy to hang out with. 奶奶, came back without any noise just now and I went to open the door and saw her belongings packed ready to move out so soon. Though it's not my own 奶奶 but still had felt sad when she hurriedly move her things and went off. She stayed here for only a week and I felt it's not that bad to let her stay here for good. She was afraid to trouble us though it wasn't at all. I knew recently something was going on between her and mum when they talked without any sound heard from far. But I did not ask mum, if she would want to tell me she would without me asking. Now,  奶奶 moved out to stay near another old lady to take care of her. I guess 奶奶 will not have much relation with us any more since she stopped working for us and even move out. Hopefully things will be fine for her and do contact mum when she in need of someone.
