My Mother's approval

Father left today for home and suddenly I feel so sad.  Although his being here had placed a lot of pressure on me (as he was then without the maid), I really wish he can stay here for the rest of his life.  I don't know why I feel this way.  Probably because I dreamt of Mother again last night, giving me a broad smile, as though she appproves of me looking after Father?   This morning I tried to persuade him to stay but he flatly refused and said "I want to go home". Why can't my house become his home?
